    Revert:
    * stmt.c (expand_nl_goto_receiver): Remove almost-copy of
    expand_builtin_setjmp_receiver.
    (expand_label): Adjust, call expand_builtin_setjmp_receiver
    with NULL for the label parameter.
    * builtins.c (expand_builtin_setjmp_receiver): Don't clobber
    the frame-pointer.  Adjust comments.
    [HAVE_builtin_setjmp_receiver]: Emit builtin_setjmp_receiver
    only if LABEL is non-NULL.
