Please don't start down this road without assembler support.  It's not
very useful to add this stuff if you can't assemble the instruction.

I'd prefer to see us disable fmpyadd/fmpysub when optimizing for the
PA8000 class machines.  See pa_reorg.

Also note, you're probably going to need an assignment if you do much
more work on the PA port.
