This change makes sure we instead add the field to the

This CL
* Removes conditional Skip markers in status files
* Removes some outdated TODOs in the code
* Deletes tests/lib_2/isolate/isolate_stress_test
=> It's skipped everywhere, we no longer support isolates on web
* Fixes standalone{,_2}/io/directory_list_sync_test:
=> Instead of relying on the Platform.script which could be an ELF
file lying somewhere else, use Platform.executable instead
* Fixes standalone{,_2}/io/unix_socket_test:
=> The server used `sub.cancel()` to close it's reading end while
the client tried to write to it. This is racy.
If the server goes first, the write on client will throw (since
no error listener was installed on socket.done)
Avoid the race by coordinating client/server.

This adds the providesSymbol method to DynamicLibrary. It returns
whether the library contains a function with the given name.
As per dlsym(3), it is valid for dlsym to return nullptr in a success
case if the symbol actually has a NULL value. So I've changed the logic
to check for dlerror() after we invoke dlsym(), both in the existing
lookup and in the new method.

On IA32 arguments are passed in registers. When a struct is returned
by value, a pointer is passed in on the stack containing the address to
which the return value is written. We did not account for this pointer
in the stack-height calculation.
This problem only surfaced when there are no arguments to the function.
Because if an argument is passed it has a higher stack height than the
pointer for the result being passed in.

However, fields which already had been transformed are indistinguishable

So instead of re-reading the information from the fields, for already

Previously, FFI store could use kUnboxedUint32 for value being stored
via 8-bit or 16-bit StoreIndexed instruction. However, such
StoreIndexed instructions require kUnboxedIntPtr representation.
Due to the mismatch in the representations, SelectRepresentations
pass inserts a speculative (deoptimizing) IntConverter instruction,
which cases crash in AOT mode. Similar problem exists for FFI loads.
This change corrects representation when unboxing value in the body
of FFI store intrinsics and when boxing the value in FFI loads,
so representation of the value matches representation required by
StoreIndexed / returned by LoadIndexed.

This CL only changes dart:ffi API, CFE, and analyzer. No VM changes
were needed because the dimensions of inline arrays can be flattened
before passing them to the VM. The multi-dimensionality does not
impact the ABI.

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

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.
Forcing the type argument to be constant and removing the runtime entry
will be done in follow up CLs.

Removing the runtime entry speeds up `.ref` significantly.
