This prevents --pause-isolates-on-start and --pause-isolates-on-exit
from impacting isolates spawned from system isolates. This should be
revisited to determine if:
- Inheriting the system isolate property is actually what we want to do
in general
- Isolate.spawn* APIs should instead include a parameter to specify an
isolate as a system isolate

I don't try to be even close to be correct here, but this is the base
on top of which I'd like to build the full implementation.
The idea is that we scan, and implement parser listener that builds
prefixed name in scopes. We fill scope with declarations as we find them. Using these scopes we can decide which import prefixes can be removed.
As usually for shared code, clients will implement abstract methods in the client specific way.
We might get a hierarchy of `Edit` objects, such as `RemoveImportPrefix` and `RemoveImportDirective` because at least in the analyzer we might need to apply some changes to the element models (metadata, constants).

According to the patterns spec, the pattern context type schema for a
cast pattern should be `_`. What was actually implemented was
`Object?`.
This is unlikely to make a difference in practice, since (a) cast
patterns are unlikely to be used in circumstances where the pattern
context type schema makes a difference, and (b) it takes some effort
to come up with expressions whose type inference behavior is differenc
between a schema of `Object?` and a schema of `_`.

The data structure in the front end for recording which getter names
can be type promoted via "field promotion",
`fieldNonPromotabilityInfo`, is a field in the `SourceLibraryBuilder`
class. This means that each library tracks its own notion of which
getter names are promotable. This makes sense because only private
getter names are eligible for field promotion, and private getter
names can only be used to access declarations in the same library.
Prior to this commit, if the user tried to perform type promotion on a
_public_ getter name, the shared flow analysis logic would correctly
deem that public name non-promotable and reject the promotion. If the
front end then called `FlowAnalysis.whyNotPromoted` (which it
typically does to get details about failed type promotions that lead
to compile-time errors), flow analysis would then use
`FlowAnalysisOperations.whyPropertyIsNotPromotable` to query the
`fieldNonPromotabilityInfo` data structure.
Since `fieldNonPromotabilityInfo` is tracked separately for each
library, if the public getter referred to a field declared in some
other library, no information would be found, so
`FlowAnalysisOperations.whyPropertyIsNotPromotable` would return
`null`. This would lead flow analysis to incorrectly conclude that the
reason for the getter name being non-promotable was due to a conflict
with some other getter with the same name in the same library, so it
would return `PropertyNotPromotedForNonInherentReason` to the front
end. The front end would then iterate through
`fieldNonPromotabilityInfo` looking for conflicting getters, again
finding nothing. This led to an assertion failure, because it doesn't
make logical sense for a getter name to be non-promotale due to
conflicts if there are no conflicts. In production builds of the front
end (with assertions disabled), the behavior was that the compile-time
error would simply have no "why not promoted" context message (which
is fairly benign, but still undesirable).
This commit fixes the bug by modifying the shared logic for
`FlowAnalysis.whyNotPromoted` so that if the getter name in question
doesn't begin with `_` (meaning it's public), then it doesn't bother
calling `FlowAnalysisOperations.whyPropertyIsNotPromotable` at all,
because it knows the non-promotion reason is because the name is
public. As a result, the correct context message gets generated, and
there is no assertion failure.
Note that the language test included in this commit doesn't check that
the correct context message is generated, because the test
infrastructure isn't capable of testing context messages that point to
other files. But it does still serve to validate that the assertion no
longer fires.

This CL optimizes how CFE et al presubmits are run.
In the examples below we'll that it takes the presubmit time from 31+
to ~13 seconds, from 31+ to ~20 seconds and from 30+ to ~19 seconds on
a few simple cases and from 76+ to ~27 seconds in a case where files in
both _fe_analyzer_shared, front_end, frontend_server and kernel are
changed.
Before this CL, if there was changes in both front_end and
frontend_server for instance it would run one smoke-test for each.
They would each technically only test things in their own directory,
but they would do a lot of overlapping work, e.g. compiling
frontend_server also compiles front_end; the startup cost of a script
is done several times etc.
The bulk of the change in this CL is thus to only run things once.
Now, if there is a change in both front_end and frontend_server the
python presubmit will still launch a script for each, but it's just a
light-weight script that will take ~400 ms to run (on my machine) if it
decides to not do anything. What it does is that it looks at the
changed files, from that it will know which presubmits will be run and
decide which of them will actually do the work - the rest will just
exit and say "it will be tested by this other one".
Furthermore it then tries to run only the smoke tests necessary.
For instance, if you have only changed a test in front_end it will only
run the spell checker (and only for that file).
Note that this is not perfect and there can be cases where you should
get a presubmit error but wont. For instance if you remove all content
from the spellchecking dictionary file it should give you lots of
spelling mistake errors, but it won't because it won't actually run the
spell checker (as no files it should spell check was changed).
Probably you have to actively try to cheat it though, so I don't see it
as a big problem. Things will still be checked fully on the CI.
Additionally
* the generated messages will have trailing commas which speeds up
formatting of the generated files (in the cases where the
generated files will have to be checked).
* the explicit creation testing tool will do the outline of everything,
but only do the bodies of the changed files.
* building the "ast model" only compiles the outline.
Left to do:
* If only changing a single test, for instance, it will only run the
spell checker on that file, but launching the isolate its run in
still takes ~7 seconds because it loads up other stuff too. Maybe we
could have special entry points for cases where it only should run an
otherwise simple test.
* The presubmit in the sdk dir (not CFE related) doesn't do well with
many (big) changed files and testing them for formatting errors can
easily take 10+ seconds (see example below where it contributes ~5
seconds for instance). Maybe `dart format` could be made faster, or
maybe the script should test more than one file at once.

Closes https://github.com/dart-lang/sdk/issues/54138
Adds a helper to do better type-checks so that users don't
accidentally using is checks or have to manually do the right
typeof or instanceof checks. In order to do this, there is
some refactoring to make ExportCreator a SharedInteropTransformer
(as it's shared across all backends) so that we can reuse an
existing visitor. In the same class, we remove unnecessary setting
of parent pointers. We should clean up the fileOffsets as well,
but dart2js verifies that those are set, so we keep them as is
for now. Also adds some static errors for edge cases.

This was a mistake in the shared logic implementation during the
implementation of patterns; instead of verifying that the for-in
expression is a subtype of `Iterable<dynamic>` (or `Stream<dynamic>`
in the case of an `await for`), it merely verifies that it's a subtype
of `Iterable<dynamic>?` (or `Stream<dynamic>?`). At some point, the
requisite error checking was added to the front end, but not to the
analyzer.
In an ideal world, the solution would be to remove the error check
from the front end and add it to the shared logic; however, doing so
is not easy, because what needs to be done is an assignability check
(as well as insertion of implicit downcasts and other coercions). The
shared logic doesn't currently have a good hook for doing that. So,
for now, this CL simply adds the requisite check to the analyzer. I
plan to try to find a clean way to share some of this logic in a
follow-up CL.

Whenever a pattern performs an implicit `is` test, flow analysis
attempts to determine whether the `is` test is guaranteed to succeed;
if it is, then flow analysis considers the code path in which the `is`
test fails to be unreachable. This allows flow analysis to recognize
switch statements that are trivially exhaustive (because one of the
cases is guaranteed to match), avoiding spurious errors such as
"variable must be assigned before use" or "missing return statement".
This change upgrades the logic for computing when an `is` test is
guaranteed to succeed, so that it accounts for type erasure of
extension types. This brings flow analysis's treatment of switch
statements into closer alignment with the exhaustiveness checker,
which should reduce the risk of confusing error messages. For more

The front end and analyzer use the same representation for types and
type schemas, with the unknown type schema (`_`) treated as a
pseudo-type. This creates the risk of accidentally mixing types and
schemas, resulting in `_` accidentally "leaking" into the type system
and showing up in static analysis results or error messages.
As a step toward reducing this risk, this change adds a type parameter
to `TypeAnalyzer`, preventing the shared type analysis code from being
able to assume that types and schemas are represented the same. This
extra discipline makes it much easier to search through the code and
identify how types are manipulated vs. how type schemas are
manipulated, and makes it impossible for the shared type analysis to
accidentally leak `_` into the type system.
I believe this change will also make it easier to implement some type
inference improvements we've been contemplating, such as improved type
inference of `.map(...).toList()`, as well as
https://github.com/dart-lang/language/issues/3471, because those
improvements may require introducing new kinds of type schemas.

According to the patterns spec
(https://github.com/dart-lang/language/blob/main/accepted/3.0/patterns/feature-specification.md),
if `A` is the type of the formal parameter of the operator
declaration, then operand should be type checked with context type
`A?` when op is `==` or `!=`, and with context type `A` otherwise.
Prior to this commit, context type `A` was always used.
There should be no observable behavior difference, because the operand
of a relational operator is required to be a constant expression, and
there is no constant expression that behaves differently when its
context is `A?` vs `A`.
However, we are contemplating some possible future language changes
that *would* make the difference observable (e.g.,
https://github.com/dart-lang/language/issues/3471), so it seems
prudent to fix the behavior to match the spec.

In https://dart-review.googlesource.com/c/sdk/+/345082, type erasure
was added to the handling of relational patterns, to address some co19
failures, e.g.:
extension type const BoolET1(bool _) {}
const True1 = BoolET1(true);
String testStatement1(bool b) {
switch (b) {
case == True1:
...
}
}
This was failing because the type of `True1` (`BoolET1`) is not
assignable to the argument type of `operator==`, which is
`Object`. (This is because extension types do not, by default, extend
`Object`; they extend `Object?`).
Adding type erasure elimited the co19 failure, but it caused other
code to be allowed that shouldn't be allowed, such as:
extension type const E(int representation) implements Object {}
class A {
bool operator <(int other) => ...;
}
const E0 = E(0);
test(A a) {
if (a case < E0) ...;
}
This shouldn't be allowed because the type expected by `A.<` is `int`;
allowing `E0` to be passed to this operator breaks extension type
encapsulation.
The correct fix is for assignability checks for `operator==` to use
`S?` rather than `S`, where `S` is the argument type of
`operator==`. This is consistent with the patterns specification, and
it ensures that `== null` and `!= null` are allowed, while continuing
to prohibit relational patterns that break extension type
encapsulation.

Do not revert: The main channel version must be upgraded now that the
version 3.3 beta has been cut and reverting this change puts the
release infrastructure into an unsupported state. Please fix forward
any potential problems that occur downstream and loop me into the
discussions so we can improve the release procedures in the future.

In order to reach parity with js_util, we expose operators
through an extension and do some partial renames in order
to make the member names sound better e.g. `equals` instead
of `equal`. We also expose the following from js_util:
- NullRejectionException
We don't expose `isJavaScriptArray` and `isJavaScriptSimpleObject`
as they can expressed through other forms of interop. There
was an esoteric bug where we needed these members for Firefox
in pkg:test, but the package no longer uses these members, so to
avoid increasing the API space too much, we do not export them.
For the same reason, we also don't expose `objectGetPrototypeOf`,
`objectPrototype`, `objectKeys`.
We don't expose `allowInteropCaptureThis` as it will take some
work to handle this in dart2wasm. That work is tracked in
https://github.com/dart-lang/sdk/issues/54381.
Lastly, `instanceof` and `instanceOfString` is moved to be on
`JSAny?`, as this operator is useful to avoid needing to
downcast to `JSObject` e.g. `any.instanceOfString('Window')`
instead of `any.typeofEquals('object') &&
(any as JSObject).instanceOfString('Window')`.
Extensions are reorganized and renamed to handle these changes.

The classes `Operations`, `TypeOperations`, and `VariableOperations`
are reworked as follows:
- The class `FlowAnalysisOperations<Variable, Type>` contains the API
used by flow analysis to manipulate the client's representation of
types and variables. This class (and the classes that support it) is
located in `flow_analysis_operations.dart`, a sibling of
`flow_analysis.dart`.
- Note that `FlowAnalysisOperations<Variable, Type>` has a supertype,
`FlowAnalysisTypeOperations<Type>`, which contains the portion of
the API that is only concerned with types. This simplifies the
implementation of flow analysis, by letting some of its lower-level
operations be agnostic to how the client represents variables.
- The class `TypeAnalyzerOperations<Variable, Type>` contains the API
used by the shared type analyzer to manipulate the client's
representation of types and variables. This class (and the classes
that support it) is located in `type_analyzer_operations.dart`, a
sibling of `type_analyzer.dart`.
- Several abstract methods and getters that were previously in the
`TypeAnalyzer` class are moved to `TypeAnalyzerOperations`, for
consistency with `FlowAnalysisOperations`.
Since the type analyzer calls out to flow analysis, the class
`TypeAnalyzerOperations` is a subtype of
`FlowAnalysisOperations`. This means that clients only need to
implement a single API, `TypeAnalyzerOperations`.

This adds a new rule to exhaustiveness handling of the as-pattern. The
new rule checks whether the cast type is fully contained in the space
of the subpattern. If so, we can assume that the whole context type has
been matched because there is no value that passes the as-test that
would be rejected by the subpattern.

Allow annotating top-level or static fields with `@Native` to create
fields backed by native memory.
By using the `_addressOf` operator implemented in the VM, these fields
can be implemented in the CFE by replacing them with accessors looking
up the pointer and then using existing methods to load and store the
value.
