This patch is OK, with one caveat: I don't understand why it's necessary
to remove REG_NOALIAS notes.  If that's not necessary to fix the test
case in question, please omit that one part of the patch.  If it is
necessary, go ahead and check in the patch, but please explain what's
going wrong there.

(The docs say that REG_NOALIAS is attached to call instructions, and
here I thought we were always looking a SET.)

Thanks,
