PATCH: Add XOP 128-bit and 256-bit support for upcoming AMD Orochi processor.

[Jakub Jelinek]

Hi!

Now that XOP support is in, shouldn't we reconsider
%{msse5:-mavx \
%n'-msse5' was removed.\n} \

in CC1_CPU_SPEC_1?  In particular, shouldn't -mavx change
there to -mxop, or -mfma4 -mxop -mlwp or something similar?
