Not fixed, just hidden.  It's a very obscure hardware bug and any sort of
shuffling around of instructions is liable to hide it.  However, it's
interesting that running post-RA scheduling changes things because that means
it has nothing to do with register allocation.  I think this is more evidence
of it being some sort of dependency-tracking bug in the hardware.

I'm re-opening this so we don't forget it's here.
