Hi!
When looking for constraints that only have x's and not v's, these
useless constraints caught my search too. In define_expand, constraints
aren't really needed, they are needed only on define_insn* etc.
So, I'd like to kill these.
Bootstrapped/regtested on x86_64-linux and i686-linux, ok for trunk?
