Johnni Winther d68f552e70 [analyzer,cfe] Handle (un)assigned state in try-statement 
This handles (un)assigned state in try-statement that do not
complete normally. In this case we could create a variable model
for an unreachable state that would be both assigned and unassigned
leading to an assertion failure.

Closes #41284

Erik Ernst f180511499 Add implementation of several parts of non-function type aliases 
Generalize `TypeAliasBuilder.unaliasDeclaration` such that it takes
an argument `typeArguments` and uses that to handle the case where
a type alias application ultimately expands to a type variable (e.g.,
with `typedef F<X> = X`, `F<int>` expands to `int`), and also to
emit a compile-time error in the case where such a type alias is
used to invoke a constructor or invoke/tear-off a static member.

Next step: Pass `List<UnresolvedType> typeArguments` from `handleSend`
to `finishSend` etc. to `BodyBuilder.buildConstructorInvocation`,
which seems to be a somewhat larger refactoring; needed in order to
make `generic_usage_class_test` pass. Some other fix is needed in
order to make `generic_usage_type_variable_test` pass.

Nate Bosch d3c0d59706 Disallow non-external generative JS constructors 
Towards #40434
Towards #38875
Fixes #33834

- Add a shared error message for a non-external constructor.
- Check for non-external non-factory constructors constructors in the JS interop
  checks.
- Remove commented out code in Dart2JS that used to handle this check.
- Clean up skipped tests due to the missing static error. The status in
  `legacy_status_dart2js.csv` has no behavior impact but is removed for
  completeness.
- Add `external` to a few test cases.
- Remove unused dart2js error message.
- Add `annotating` to hardcoded spelling list.
- Ignore missing example for web specific error message.
- Switch some dart2js error expectations to GENERIC since the message is no
  longer defined with other dart2js errors.

Non-external synthetic constructors are ignored for now. An upcoming change will
automatically convert these to external.

Jens Johansen 3660b9ecc7 [parser] New syntax for null aware index (2nd try) 
This reverts commit bc4893a3b3.

The previous attempt failed because when we check if something is a
conditional expression we used a rewriter that didn't actually rewrite.
This further down the line (still checking if we can parse the expression)
results in errors occurring (that wouldn't have occurred if the rewrite
had happened) and the conclusion was thus that it wasn't a conditional
expression and we parsed it as a null-aware index operator (which gave
errors because it wasn't).

This 2nd try solves it by having a rewriter that actually rewrites,
but then allows to undo the rewrites after we're done parsing.
