Jens Johansen 22d75929bd [CFE/VM] Fix location on ffi native procedure; pass reference
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.

David Morgan f1f188cd96 [macros] Split out modular parts of package:vm into package:vm/modular.
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.

Martin Kustermann c0371169b0 Cleanup some code regarding deprecated native syntax
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.

This was caused by an update on the flutter side, where a dependency

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.

Chloe Stefantsova 72860d3569 [cfe] Use declaredNullability to carry over in type substitutions
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`.

Jens Johansen 7e792e7a8b [kernel/DDC] Fix failing DDC tests; if finding no scope for offset find for a close previous offset instead
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.

Chloe Stefantsova 3eeba4a4e2 [cfe] Refactor FunctionNode.futureValueType into emitted value type
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`.

Paul Berry 949f3af120 Remove kernel flag Procedure.isAbstractFieldAccessor.
This used to be used solely by field promotion, to recognize when a
getter arose from a declaration of an abstract field, so that abstract
fields would be promotable but explicitly declared abstract getters
would not be.

However, with the adoption of
https://github.com/dart-lang/language/issues/3328, both abstract
fields and abstract getters are now considered promotable, so there is
no longer any need to distinguish them.

```
out/ReleaseX64/dart-sdk/bin/dart compile aot-snapshot \
  pkg/front_end/tool/_fasta/compile.dart
```

and then moved to `pkg/front_end/tool/_fasta/compile.org`,
then benchmarks run like

```
rm /path/to/other/checkout/pkg/front_end/tool/_fasta/compile.dart.dill ; \
  rm pkg/front_end/tool/_fasta/compile.aot ; \
  out/ReleaseX64/dart-sdk/bin/dart compile aot-snapshot \

  --arguments=/path/to/other/checkout/pkg/front_end/tool/_fasta/compile.dart \
  --filesize=/path/to/other/checkout/pkg/front_end/tool/_fasta/compile.dart.dill
```

(The other checkout is at 8b01baab71)

I get this:

```

Will now run 50 iterations with 2 snapshots.

```

So `instructions:u` being the most stable says a reduction of 1.42%,
time is in that range too (-1.9077% +/- 0.5801%), although in both
cases some of it is likely the number of new space GCs going from

Jens Johansen ed64348f68 [kernel] Calculate scopes for expression evaluation differently
This CL introduces an alternative way to calculate scopes for
expression evaluations. Currently the previous method is kept as well.

What this does is that it:

* Finds all nodes that match the offset and uri. (Ideally there's only
  one, but that's not always the case --- it's the case for less than
  60% of cases in the test added actually).
* Calculate the scope along the way.
* Return the scopes of all the found nodes that offset.

A test that asks for ~all file offsets in the dill files in the sdk and
compares the result with the scope the binary serialization computes is
added.
A single point can't always be found (for all dills in the sdk
only ~58.93% returns a single result), but for each query the wanted
scope is among the results returned.
For the non-outline dills in the sdk, between ~87.93% and ~94.52% of
the results are either a single result or multiple results with the
same actual scope in all of them.

Note that the test asks for ~all offsets, not just "debuggable" or
"stopable" offsets (which will likely vary depending on the vm/web
backend etc) --- likely the percentage will be higher for those points
though.

When this returns multiple results one can likely be picked by the
client based on information it has about names of variables in scope
etc.

Note that the test is rather slow, on my machine with the platforms
available there it makes 3,908,181 queries in ~3.5 minutes.
(Which corresponds to roughly 18,610 per second or under 0.06 ms per
query on average though, so it doesn't seem like a concert for actually
using it.)
