Thanks for pointing this out, Pat.  Your patch could fix this particular problem
but using GENERAL_REGS only is wrong.  The final allocno class should be
NON_SPECIAL_REGS.  I will search for a better solution.  Unfortunately, such
changes in the code should be benchmarked on a few major targets.  So it will
take some time (a weak or two) to fix the problem.

Ok, thanks. I can lend a hand with any PowerPC testing if you want.
