[PATCH] improve copysign, parity on power6/power7 systems


This patch improves the PowerPC compiler to use the fcpsgn instruction for the
copysign builtin and prtyd/prtyw instructions for the parity builtin that were
introduced in the power6.

I have done bootstrap builds and make check for C, C++, and Fortran with no
regressions with this patch.  Is it ok to install?
