[PATCH] additional bit values for cpuid.h

[Jonathan Gray]

The attached patch adds some additional Intel cpuid values and adds
aliases for some defines used by the equivalent gcc header.

The bit_SSE4_1 and bit_SSE4_2 aliases in particular would be
useful for Mesa and xf86-video-intel which currently define
their own values due to the mismatch between clang and gcc.
