Adds support for single dimension inline arrays in structs. Multi-
dimensional arrays will be supported in a future CL.
This CL adds:
- CFE static error checks for inline arrays.
- CFE transformations for inline arrays.
- VM consumption of inline array fields for NativeType.
- Test generator support for inline arrays + generated tests.
Previous CLs added support for inline arrays in:
- analyzer https://dart-review.googlesource.com/c/sdk/+/183684
- updated in this CL to new API.
- ABI calculation https://dart-review.googlesource.com/c/sdk/+/183682
Closes: https://github.com/dart-lang/sdk/issues/35763
Open issue: https://github.com/dart-lang/sdk/issues/45101
CFE transformations are tested with expectation files:
TEST=pkg/front_end/testcases/(.*)/ffi_struct_inline_array.dart
Trampolines and CArray API are tested with end-to-end Dart tests:
TEST=tests/ffi(_2)/(.*)by_value(.*)test.dart
TEST=tests/ffi(_2)/inline_array_test.dart
Compile-time errors (both CFE and analyzer) are tested in:
TEST=tests/ffi(_2)/vmspecific_static_checks_test.dart

The non-function type alias feature will no longer be supported in
legacy code. This CL moves all the tests on this topic in language_2
to language/nonfunction_type_aliases/mixed. This CL also splits each
of the tests in a legacy part (with @dart and Requirements) and a part
with null safety (containing the non-function type alias declarations
and a bit of code that it depends on), such that we are testing that
non-function type aliases can be used in mixed-version programs, as
long as they are declared in an opted-in library.

If an operator declaration has both too many parameters, and one or more
optional parameters, just report the former error.
This is better UX, and is closer aligned to what the CFE reports.

Since the flag is now enabled by default, there should be no mention of it.
There are still some uses in front_end/testcases that are not just removable
(it also uses `no-non-nullable`). There migth be more uses that are not
as easily found as grepping for `--enable-experiment
Removes two VM tests where fixing them meant they were just duplicating

JSDouble represents doubles that are not integers. It is usually wrong
to use JSDouble, so use JSNumber instead where we mean 'all double
values'.
This fixes#44818 by not mistakenly pretending that division cannot
have an integral result.
Will follow up with a CL to rename JSDouble.

This CL avoids creating locals using KernelToLocalsMap when computing
closure data for the J-model. Instead the closure data uses
ir.VariableDeclaration, JTypeVariable, and internal locals (ThisLocal
and BoxLocal) internally, and the accessor function require passes
a KernelToLocalsMap to convert the internal model to a Locals upon use.
The converted Locals are cached internal for performance only.
This prepares for splitting the GlobalLocalsMap and KernelToLocalsMap
from the JClosedWorld.

Currently we don't support generic metadata, but we'll be adding
support soon (https://github.com/dart-lang/language/issues/1297).
When we add it, we'll still want to have tests to make sure that it's
not allowed in older language versions.
The tests we currently have to make sure it's not allowed only test
annotations occurring outside of function bodies, however the front
end code paths for handling code inside function bodies are
sufficiently different that it makes sense to test inside function
bodies too.

This check was previously introduced without a language version,
and therefore lead to a breaking change on SDK update. It's now
versioned for releases >= 2.13, allowing users to migrate easier.
It also adds a hint for the error, providing alternatives for
users whose code triggers this check.

Also removes duplicate checks in dart2js for non-native external

This rewrites `Pointer<Struct>.ref` and `Pointer<Struct>[]` calls in
the CFE to skip the runtime entry when the type argument is constant.
The runtime entry is still used when the type argument is generic.
