   I pondered doing this briefly, but when I looked at the profiling data it
   just didn't seem worth the effort.

   From the profiling data it doesn't appear to be worth it -- once you're sharing
   regno_raw_mode hard regs you've got 99% of the benefit of sharing hard regs.

See my other email for why I also care about the low-profile cases
as well as the really high count ones :-)
