Dart Byte Code interpreter.
...
This version is Clang/GCC only and does not support Windows because it uses computed goto's.
Only unoptimized mode is supported.
Architecture is described in constants_dbc.h and stack_frame_dbc.h.

VM: Refactor assembler test that rely on the constant pool.
...
This makes the test code independent of the way we call Dart code and
makes it easier to change the calling convention.
The code for calling test code is now encapsulated in unit_test.h instead
of being spread over many different files.
I only changed the tests that need a constant pool set up, but the same strategy
could be used for all other assembler tests to avoid unnecessary duplicated
boilerplate code.

Cache current thread in a reserved register and use it in LoadIsolate
...
Add THR register that caches the current thread in generated code.
Shuffle some registers around as needed to free one up.
Note: Assembler::LoadIsolate now always loads the *current* isolate whenever the code is executed, rather than the isolate in which the code was compiled (no existing code was affected by this slight change in semantics).
Rewrite some ia32 stubs to use one less register, and for some ia32 bigint intrinsics, explicitly save THR (like CTX in the past, see r44699).
Next steps:
- pass current thread rather than isolate in NativeArguments
- ditto for exception handler jump
- migrate fields vm_tag, top_exit_frame_info, etc. to thread

Begins work on ARM64, first assembler test.
...
Most new code is in constants_arm64.h and
{assembler,disassembler,simulator}_arm64.{h,cc}
The rest of the CL just #def's out tests, modifies status files,
and adds UNIMPLEMENTED functions, etc.

- Remember the fact that an object has been added to the
...
store buffer by a bit in the header.
- This bit can be used to filter out redundant additions
into the store buffer making the dedup sets not needed.
- Remove the need for a HashSet when remembering old to
new references.
