> All header files should be self-contained. Users and refactoring tools should not have to adhere to special conditions to include the header. Specifically, a header should have header guards and include all other headers it needs.
This cleans up header files referring to types and functions defined in the files including those header files.
This does not clean up the include guards in xyz_<arch>.h. We have currently 45 such include guards. We can clean that up by moving the #ifdefs from xyz.h to the individual xyz_<arch>.h files. A list of header files which cannot stand on itself is maintained in runtime/tools/run_clang_tidy.dart.

Sign extension of small integers is not symmetric between register arguments and register return values.
On Linux/MacOS x64, the caller is responsible for both the arguments and return value.
Previous tests only tested equality, which tests the equality of the lowest byte. However, when printing or using the small ints arithmetic all 4 bytes are used. The new tests pass back the number in a different format.
The callback tests test the number in Dart, so they did not suffer from implicit conversions. (TestTakeMaxUint8x10 in runtime/bin/ffi_test/ffi_test_functions.cc and tests/ffi_2/function_callbacks_test.dart.)

Introduces NativeRepresentation and NativeLocation for the compilation of FFI.
NativeRepresentations are able to express all representations (or types) of the native ABIs we bind to with FFI, this is more representations that than that are used in Dart itself.
NativeLocations are able to express all locations of the native ABIs we bind to with FFI, this is more types of locations than that are used for the Dart calling convention.
See the documentation in the respective files.
These NativeLocations and NativeRepresentations are computed by the NativeCallingConvention and consumed by the Marshaller and Assemblers.
This reenginering is required for go/dart-ffi-by-value, hardfp (Arm S and D fpu registers), and iOS 64 bit (non-word-aligned stack arguments).
In addition, by using the NativeRepresentations we also get slightly reduced code size:
* The tracking of sizes is improved, so less sign/zero-extension operations are required.
* UnboxedWidthExtenderInstr is fully removed, the size extension is done inside the native moves, coalescing moves and size extension when possible.
* BitCastInstr is only used when really needed. This reduces code-size on arm32 softfp.
This fixes the iOS arm64 calling convention, manually tested with https://github.com/flutter/flutter/pull/46078 and https://dart-review.googlesource.com/c/sdk/+/131074.

1. Fix SIMARM_X64 build: no need to generate trampolines for AOT or simulated JIT.
2. Hot-reload: Fix hot-reload: don't invalidate Code for force-optimized functions.
3. Windows: Provide shadow space to runtime routines.

There is no difference from the previous version of this CL.
This depends on https://dart-review.googlesource.com/c/sdk/+/67220/3 which fixes a bug
in `CompileType` that was causing `ShouldEmitStoreBarrier()` to return different results
across multiple calls on the same instruction.
The buildbot on which this caused a failure is run as a tryjob below.
