Thanks for looking to this.  No bootstrap unfortunately, but I can
regression-test it for cris-elf, which should be sufficient.  Well, I'm quite
certain you too know exactly the steps ;-) but I guess since I have a baseline
and a setup...

Let me just suggest changing the "... == 0" to "... == NULL_RTX" in the last
part of the patch.  To incentivise, I'll test that. :)
