Original Commit Message:

    This changes Generate_ContinueToBuiltinHelper to generate code to load
    the builtin address directly from the builtins table rather than going
    via the executable code in the trampoline's code object.

    The set up for Generate_ContinueToBuiltinHelper is changed so that the
    builtin index is stored on the stack in place of the builtin Code
    object which is no longer needed.
