The dart2wasm compiler treats wasm arrays of objects/ints/floats pretty
much the same, there's no reason to have complicated class hierarchy and
different kinds of wasm array classes.
Also: We rely on all operations on wasm arrays (and other built-in
types) to be handled on the call site. Wasm arrays are not dart objects,
don't support virtual dispatch. So we make operations operating on the
wasm types extensions.
This also makes now loads and stores into the wasm arrays simple `[]` and
`[]=` operations. We still have special extensions for reading/writing
to integer/double arrays that not only read/write but also
sign-extend/zero-extend and operate on Dart's `int` / `double`.
The compiler will allow `WasmArray<X>(length)` for types `X` that have
default-value in wasm arrays (nullable / integer / double types) and
have another `WasmArray<X>.filled(length, X)` for non-nullable reference
types.
Overall this reduces LOCs and simplifies things

Refactor libraries so that JSCM will only use `JSStringImpl` class for
strings.
The goal is to disentangle the native string classes and `JSStringImpl`
and start testing `JSStringImpl` in isolation.
Changes:
- `dart:_string` is no longer available in JSCM.
- Make `int.toString` external to allow patching it differently in JSCM
and normal modes.
`toString` implementations are in `boxed_int_to_string.dart` patch
files.
- `int.parse` now uses JS `parseInt`. However `parseInt` is not
compatible with Dart's `int.parse` so this will cause some more test
failures in JSCM for now.
- Any dependencies to `dart:_string` from JSCM `dart:convert` are
removed. The library implementation now uses JS `TextDecoder` for
UTF-8 decoding.
Note: `TextDecoder` is not available on d8, so text decoding tests
will fail on d8.
JSON encoding and decoding in `dart:convert` will be updated in a
follow-up CL.
- Compiler (translator, constant generator, code generator etc.) is
updated to allocate the `JSStringImpl`s in JSCM.
Initially this will make some JSCM test fail as `int` parsing is not
quite right, those will be fixed in follow-up CLs.

This was originally implemented in a289c4d but then reverted in dc33261
as it broke Flutter: https://github.com/flutter/flutter/issues/124282.
The problematic code in Flutter was updated, so landing the fix again.
Original commit message:
`emitTypeTest` optimizes a test like `x is List<T>` where `x :
Iterable<T>`, i.e. tested-against type is a subtype of the operand's
static type. In these cases we can check just the class ID of the
operand without checking the type arguments.
However this optimization cannot be done when the types don't have same
number of type arguments. Example:
class H1<T> {}
bool test(Object o) {
return o is H1<num>;
}
void main() {
print(test(H1<Object>()));
}
Here `H1<num> <: Object`, but we still need to check the type parameter.
This CL checks that the types have the same number of type arguments
before optimizing the test.
Fixes#51187.
This fix reveals another bug in `static_interop_test`, which is tracked
in #51200. The test is updated to work around the bug for now.

The desugared code uses `Completer<bool>` values to suspend the `async*`
function, but we can't use a type test and to check if a value is the
`Completer<bool>` value for the suspension or a user-emitted value as
the `async*` function can also yield `Completer<bool>` values. Update
the test from `value is Completer<bool>` to `!isEven`.

This reverts commit 49f85335d5.
Reason for revert: Fixes the original breakage by adding an explicit
cast for the map function that's used to compute positional args
of the stub. Adds refactoring to better separate out the logic
between procedure-level and invocation-level lowering configs.
Also refactors optional argument functions so that they can use the
invocation-level lowering configs created in this CL. Also fixes
a small issue where object literal constructors wouldn't work in
dart2js if the surrounding library didn't have a @JS annotation.

Adds class modifiers to `dart:ffi`.
Migrates all user-defined subclasses of `Struct`, `Union`, `Opaque`,
and `AbiSpecificInteger` to be `final class`es.
Does not remove the manual error checking, so some errors will show up
twice now in language version 3.0. In language version <3.0, only the
FFI-specific error will show up.
In a follow-up CL, we will try to make the language-errors to show up

This reverts commit 1f6d4ae1a8.
Reason for revert: Broke Flutter with dart2wasm
Original change's description:
> [dart:js_interop] Add literal constructors for inline classes
>
> Adds @ObjectLiteral annotation to denote object literal constructors,
> and implements it in all the backends. For dart2js, this involves
> modifying the SSA and for dart2wasm, we create a one-per-shape
> forwarding procedure to a specialized JS method that returns the
> literal. This also modifies @anonymous semantics in dart2wasm to
> be consistent with the other backends.
>
> CoreLibraryReviewExempt: Backend-specific, just adding annotation.

Adds @ObjectLiteral annotation to denote object literal constructors,
and implements it in all the backends. For dart2js, this involves
modifying the SSA and for dart2wasm, we create a one-per-shape
forwarding procedure to a specialized JS method that returns the
literal. This also modifies @anonymous semantics in dart2wasm to
be consistent with the other backends.

Since Dart `void` can actually carry values, functions with `void`
return type are translated into Wasm functions returning the Dart
object top type instead of an empty output type list.
Only constructors, setters and imports/exports with void return type
are now given empty output type lists in their Wasm signatures. A new
low-level `WasmVoid` type is added to the internal Wasm types for
specifying explicitly that a Wasm function should have an empty list
of outputs.
Fixes https://github.com/dart-lang/sdk/issues/50458
CoreLibraryReviewExempt: Only changes Wasm-specific libraries.

This CL also adds changes how static interop objects are interpreted at the interop boundary. Previously, static interop objects were dartified / jsified like everything else. Now, they are simply boxed.
With this approach, users can now use `Object` when they want conversions and static interop objects when they don't(assuming these objects originate in JS, Dart objects are always fully converted).

Also implements various related changes to the WasmGC spec:
- Remove `dataref` and add `structref` and `arrayref`.
- Use new encoding for `array.len` without immediate.

It's a bug if a class has more than one `@AbiSpecificIntegerMapping`
annotation. Reflect this in the return type of method for getting the
annotation and issue a diagnostic if the invariant doesn't hold.
The invariant is checked by `_FfiDefinitionTransformer`.

This CL introduces a new kernel-to-kernel pass in Wasm backend to
compile `FfiNative`-annotated external functions to external functions
with `wasm:import` pragmas.
The new pass `WasmFfiNativeTransformer` extends `FfiNativeTransformer`.
Some `FfiNativeTransformer` methods made public to allow reuse in the
pass.
The conversion works like this: when we see a member like:
@FfiNative<Int8 Function(Int8, Int8)>("ffi.addInt8")
external int addInt8(int a, int b);
We generate a Wasm import using Wasm ABI types according to emscripten
calling conventions:
@pragma('wasm:import', 'ffi.addInt8')
external static WasmI32 addInt8_$import(WasmI32 a, WasmI32 b);
and convert the original member (`addInt8()`) to a wrapper function that
calls the Wasm import, converting the arguments and return values to
Dart types:
static int addInt8(int a, int b) {
return WasmI32.toIntSigned(
addInt8_$import(
WasmI32::int8FromInt(a),
WasmI32::int8FromInt(b),
));
}
Build, test, and CI changes:
- Test runner now uses `// SharedObjects=...` lines in dart2wasm tests
to pass extra Wasm modules to d8 command used to run the tests.
Support for `// SharedObjects=...` lines were already used in
native/AOT FFI tests, not added in this CL. We just start to use those
lines in dart2wasm tests.
- dart2wasm gn file updated with a target "test_wasm_modules" that
builds FFI test Wasm modules to Wasm using emcc (emscripten C
compiler).
- CI dart2wasm_hostasserts configuration updated to copy the Wasm files
generated by the "test_wasm_modules" target to the shards.
