Omit JIT compiler from precompiled runtime on ARM, ARM64 and IA32.
...
Saves about a megabyte on the size of the precompiled runtime VM.
Next step will be to eliminate the assemblers and code stubs as well. This requires some more disentangling.
Until then, the X64 build still includes the compiler, since its assembler has a dependency on locations.cc, which is part of the compiler.

Thread/Isolate refactoring: new(Isolate*) -> new(Zone*)
...
Refactor all remaning cases where the current zone is used through new(Isolate*) and remove this interface.
Removing this interface is needed to move towards multiple threads per isolate, and also makes the caller more aware of the scope of the zone used, reducing the risk of use-after-free.
Make the current thread and the stack zone created around native/runtime entries directly available in their body, saving an indirection (and optimized away if unused).

Copy irregexp related code from V8.
...
This "syntactic" change copies the irregexp code from V8 r24065 to Dart.
Compared to the V8 files the only changes are that the files have been
suitably renamed, headers and footers have been updated, and most of the
unneeded code has been replaced by a 'SNIP' marker. None of the files
are added to the build and they cannot compile. Integration with the
Dart VM is done in a follow-up CL [1].
