   There was one problem in the mips.md file.  I have checked in a
   patch to fix it.

I've just fixed the violations in the sparc.md file as well.
I did this only for the mainline for the moment as it seems only
new patterns I introduced in the sparc backend rewrite have this
problem, but I'll doublecheck the 1.1 branch later just in case.

Later,
