Yes, it does make sense.  I must've missed it, since I was updating
similar cases all around the file.
It should not be code correcntess issue, just code quality - we still
rely on REG_N_CALLS when asking if register crosses a call, just use
frequency to drive decision on profitability of using caller save
register.

Thanks!  I will also look into the two regressions this afternoon unless
you beat me.
