Q. Are there other hunks of the regclass pass which modify the number of
times a register is referenced or set? If so, then it might just be
easier to rerun the code which computes the reference counts.
Regardless, I consider the patch Daniel checked in to fix this problem OK
for the branch too. I don't know if the branch is open for checkins or not
though.
