description:
Pull up revision 1.3 (requested by skrll in ticket #1699):
Fix a bug WRT -vomit-frame-pointer -- use_return_insn() must return false if
we saved the GOT pointer register.
Note: This is already fixed in the GCC 3 sources, but GCC 3 uses a different
condition to determine whether to save and restore the register, so the patch
cannot be the same.
