Previously the code range could be allocated close but still outside
of the "short builtins call" region which would enforce copying of
builtins blob into the code range.
This CL ensures that the calculated hint address takes the required
base alignment into account and thus allocates the core range inside
of preferred region (see Isolate::GetShortBuiltinsCallRegion()).
