      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.
