Clement Skau b681bfd8d2 [VM] Fixes bad reuse/typing of temps in async transform invocations. 
For a method invocation temps might get allocated for both the receiver
and argument(s) so that:
  A().foo(await null)
becomes:
  Future<void> tmp0
  ...
  tmp0 = A() // <- Type mismatch.
  yield ...
  tmp0 = tmp0.foo(:result) // <- Correct type.

This happens because the liveness analysis finds that the (previously
dynamic) temps can be reused.
Unfortunately 121988 added typing information to these temps, which
means they can't be simply reused in all cases.

This fix makes the temps dynamic again (by removing the type) but adds
unsafecasts to all VariableGets to propagate the know type.

Use the version from tools/experimental_features.yaml as the current
language version (as specified in kernel).

Use the "enabledIn" from tools/experimental_features.yaml to write out
the major and minor version for enabling features. This replaces the
hard-coding of when nnbd is enabled (in front-end).

Alexander Markov 88be7d1cae [cfe] Fix hasImplicitSetter for late final fields 
Unlike other final fields, late final fields without initializers have a
corresponding implicit setter. Previously, front-end was setting
Field.hasImplicitSetter to false for late final fields.
As a result, ClassHierarchy.getDispatchTarget was not returning such
field as a dispatch target for a setter invocation and TFA was inferring
incorrect types for late final fields (as if all setters for late
final fields disappeared).

Certain nodes will delimit(..) an Expression to some Statements, which
was resetting the temp nameIndex.
This meant any sub-expressions that generated temps would not cause the

Jens Johansen 8d11c1dce6 [kernel][vm] Add uris only from mixins to libraries sourceReferences 
index to fix VMs coverage issue

This CL fixes the VM not always reporting coverage for mixin usages
properly.

* When asking the VM for coverage you can do it in one of two ways
  * Ask the VM for coverage for everything; or
  * Ask the VM for coverage for a specific script
* Asking the VM for coverage for everything works perfectly fine.
  The VM goes through everything and reports coverage correctly.
* Asking the VM for coverage for a specific script (which is, at least
  now, what the flutter tools does) doesn't work in the simple mixin
  case described at http://dartbug.com/39779: The VM goes through the
  libraries, asking for the list of scripts they "know about",
  and checks for matches against what you asked for.
  In this case, when asking for 'master.dart', the library for
  'lib.dart' says no when it shouldn't --- because of the way the mixin
  transformation works the content is actually in lib.dart.

This CL updates the content of the field 'sourceReferences' on Library
to fix the issue.


Fixes #39779
