Address all warnings and errors in positive tests.
Move all static checks tests to tests/ffi/static_checks/ so it's
easier to ignore them in the analyzer.

Analyzer fix https://github.com/dart-lang/sdk/issues/54754 has
landed. A new version of package:analyzer and package:dartdoc have
been released. `pub global activate dartdoc` should now work.
Patchset 1 is identical to the original CL.
The only difference is an extra test testing with negative offsets.
=== Original CL description ===
Structs and unions can now be created from an existing typed data
with the new `create` methods.
The typed data argument to these `create` methods is optional. If
the typed data argument is omitted, a new typed data of the right
size will be allocated.
Compound field reads and writes are unchecked. (These are
TypedDataBase loads and stores, rather than TypedData loads and stores.
And Pointers have no byte length.) Therefore the `create` method taking
existing TypedData objects check whether the length in bytes it at
least the size of the compound.

This reverts commit c2e15cff6d.
Reason for revert: https://github.com/dart-lang/sdk/issues/54754
Version skew somewhere in the analyzer/dartdoc/flutter combination.
We need to land the fix inside ffi_verifier.dart first, and then
reland the API docs that trigger the code path in the analyzer
that throws the exception.

Both `sizeOf` and `AllocatorAlloc.call` use the new type as bound.
This prevents runtime errors on trying to call these two static
methods with unsized native types. All tests testing for these runtime
errors have been deleted.
The `NativeTypes` implementing `SizedNativeType` are as follows:
* The native integer types, `Float`, and `Double`.
* `AbiSpecificInteger` and it's subtypes.
* `Struct` and `Union` and their subtypes. The
The `NativeTypes` not implementing `SizedNativeType` are as follows:
* `Void` has no size.
* `Opaque` and subtypes have unknown size.
* `Handle` is considered opaque. Cannot be used as field in compounds.
* `Array` does not carry a size in its type. Can be used as fields in
compounds with an annotation specifying the size.
* `NativeFunction` is considered opaque. Would have variable size.
* `VarArgs` is only a marker in function signatures.
`Struct`s and `Union`s can have only `SizedNativeType`s and `Array`s
as fields. Documentation for these is in flux in another CL, so we
should update it there.
This CL also replaces a bunch of `extends NativeType` with
`implements` clauses and made `NativeType` itself `abstract`.

The `tests/ffi/prepare_flutter_bundle.dart` script will try to discover
all synchronous, positive test from the "ffi" test suite, rewrite them
slightly and output a directory which can be used in a flutter/flutter
FFI integration test.
We split the ffi test functions into two parts, because a subset of the
C functions will issue calls to the VM via `dart_api.h`, which is not
available for the flutter/flutter integration test.
=> We make `runtime/bin/ffi_test/ffi_test_functions.cc` a pure C
library, usable without `dart_api.h` and move the remaining VM
specific code to .../ffi_test_functions_special.cc contains.
All tests from `tests/ffi/*_test.dart` will be included in the generated
bundle, which
* don't use async/isolates
* don't rely on VM api
* don't rely on DynamicLibrary.{process,executable}
* don't take too long to execute
The script can be used as follows:

Original CL in patchset 1.
Fix for simdbc in patchset 4.
Fix for arm32 precompiled in: https://dart-review.googlesource.com/c/sdk/+/120660/
This CL optimizes Pointer operations in hot loops for Pointer<NativeInteger/NativeDouble/Pointer> (not for structs).
Design: go/dart-ffi-pointers-il
It provides roughly a 100x speedup for the FfiMemory benchmark. The next 5x speedup is to get rid of allocations due to `load` and `store` not being inlined.
FFI API is changed to enable optimizations:
* Disable dynamic invocations of Pointer.load / Pointer.store.
* Disallow implicit downcast of argument passed to Pointer.store.
* Stop zeroing out Pointer.address on Pointer.free().

* Move FFI tests into a separate test suite.
They never belonged in standalone_2/ since they are not only available in
the standalone VM. Also, we want to have a separate status file.
* Add new "SharedObjects" option to test files to copy needed shared objects
to the Android device for testing.
* Add support to compiler/runtime_configuration.dart for testing JIT-mode on Android.
* Add new configurations and builders to test_matrix.json to test JIT-mode on Android.
* Clean up status file entries for FFI (we didn't need to special-case stress & subtype tests).
