MIPS64: Fix '[stubs] Introduce a dedicated FastNewObjectStub.'

Port ba2077aac3a775523ca3fc9600fcf76f55e8d1c2

Original commit message:
Move the already existing fast case for %NewObject into a dedicated
FastNewObjectStub that we can utilize in places where we would otherwise
fallback to %NewObject immediately, which is rather expensive.

Also use FastNewObjectStub as the generic implementation of JSCreate,
which should make constructor inlining based on SharedFunctionInfo (w/o
specializing to a concrete closure) viable soon.
