The existing implementation assumed, hardcoded, that the compilation
environment had an entry for any string of the form `dart.library.`+X,
with a value of either `"true"` or `""`.
This did not match the runtime behavior of the standalone VM,
which allows non-constant access to the compilation environment.
Changed to only have entries with value `"true"` for libraries
which exist.
This changes the value of `bool.hasEnvironment` or a
`String.fromEnvironment` or `bool.fromEnvironment` with a
non-default `defaultValue`.
The existing behavior was that `bool.hasEnvironment` was always true,
and that the other constructors ignored the `defaultValue`,
so most likely such tests or `defaultValues` aren't used anyway.

Before this CL the FFI external transformation set a wrong file uri on
the created procedure when the field it came from was in a part.
Possibly this is what caused
https://github.com/flutter/flutter/issues/144176
Adding a CFE test it also surfaced there not being passed a reference.
As I recall we technically disable 'advanced invaclidation' for ffi
stuff so maybe it doesn't matter, but it was easy to add and now the
test is happy.
Tested: Existing test + CFE test added.

The modular parts in package:vm/modular/** will only depend on
* package:kernel
* package:front_end
=> Only for auto-generated error code messages
=> Those error codes can be their own dart_library() in g3
Based on https://dart-review.googlesource.com/c/sdk/+/353980, with
changes:
* Exclude package:kernel from "no exports" CFE presubmit.
* Add package:vm/modular to CFE "allowed deps".
* Fix import in `front_end/tool/perf_common.dart` and various others.
Tested: no code changes, only moves.

This adds support for generating the merged augmentation library in the
CFE. In order to get the right file offsets in the generated AST the
MacroExecutor.buildArgumentationLibrary function is extended to compute
a list of spans the describe what each segment of the generated source
code contains. These spans are used to compute the offset relation
between the intermediate augmentation libraries and the merged
augmentation libraries.

The VM target no longer supports the `foo() native "foo";` syntax. See
final removal in [0].
Dart2Wasm has never really been using it.
* In the sdk dart2wasm uses `external` functions with
recognizion in the compiler based on the name of the method.
* JS interop is using `@JS` based mechanism.
* Wasm to Wasm interop is based on `@Native<>()` annotations.
This means that only dart2js/ddc are remaining users of the
`foo() native;` syntax (without following string).
So we can clean up some code.

Over the weekend the flutter-frontend bot started failing.
This was caused by an update on the flutter side, where a dependency
started using extension types, and revealed a bug with relinking on our
side.
This CL fixes the bug which should make the bot succeed again (as well
as, I think, fix a potential leak/failure if rejecting an advanced
invalidated incremental compilation.
I will add tests in an upcoming CL.

Previously we would use the value of the `nullability` getter as
the carry over nullablity for the substituted type. This CL changes
that to `declaredNullability`. The change is observable in
substituted extension types: their `nullability` is a combination
of the representation type nullability and the declared nullability,
and its value range includes `Nullability.undetermined`, which should
not be available for `ExtensionType.declaredNullability`.
The unexpected value for `ExtensionType.declaredNullability` was
detected by the assert in
`_NullabilityMarkerDetector.visitExtensionType`.

This change is needed as a prestep to adding the package:macros and using it in the CFE and analyzer, and needs to be rolled in as the checked in sdk before package:macros can be supported.

When landing https://dart-review.googlesource.com/c/sdk/+/342400
the ddc-mac builder (but not Linux and Windows) started failing.
I could reproduce on Linux though so I'm not sure why those builders
didn't fail (nor why it wasn't caught by the try bot), either way this
fixes the issues:
* Test update: E.g. a breakpoint at the end of the scope doesn't work
because it will not be inside the (wanted) scope.
* Test update: Evalating "this" now actually works.
* Scope finding update: DDC adds sourcemapping entries for the *end* of
things so e.g. the getter "c" will have offset and offset+1 added as
source mappings. When translating from javascript position to dart
position we might pick that and thus ask for the scope of offset+1,
but nothing will be found because no node has that offset.
Here I add a fall-back saying that if we get no results we ask again
for the nearest lower offset.

This allows using the new scope finder and facilitates expression
compilation with and in extension types.
For now the script uri is optional (and only passable in the new json
input via package:frontend_server), and only if the script uri is passed
we'll use the new scope finder.
Flutter etc should be updated to pass the new data.

Previously we would encode the type of the value returned in `async`
functions as the field `futureValueType` on `FunctionNode`. For all
other kinds of functions, such as `sync`, `sync*`, and `async*`, that
field would be null. This CL renames `futureValueType` into
`emittedVAlueType`, and for functions of kinds `async`, `sync*`, and
`async*` that is expected to be the type of values emitted via
`return` or `yield` statements. For `sync` functions that field is
supposed to contain `null`.

General approach: Find all scopes for an offset,
then pick "the right one".
This still leaves a few offsets where we can't pick 1 scope in the
