PPC: HydrogenCodeStubs consume stack arguments via descriptor.

Port 3334b830

Original commit message;
    All of this is controlled by the CallDescriptor. It's simply the case
    that if you specify less registers than the function arity calls for,
    the rest are assumed to be on the stack.

    Bailout handlers accept these constant stack arguments too.
