Original issue's description:
> [builtins] Introduce a builtin for Abort().
>
> Calling Runtime::kAbort through a builtin instead of the c-entry stub
> will allow to generate the call in a background thread, because a
> builtin provides its own handle, whereas a code stub does not.
>
> @v8-mips-ports: Could you take a special look at the padding that is
> done in MacroAssembler::Abort()?
