   Erhm...  It appears to me that using shared hard reg rtx is not
   appropriate in reload, since regrename modifies regs in place.  What
   am I missing?

Jeff's changes only work on hard registers.  Reload never renumbers
things that start out as hard registers or else we'd have all sorts of
regression test and bootstrap failures from his changes.
