SVN rev 222043 on 2011-05-17 22:36:16Z by jkim
Update CPUID bits to reflect AMD Bulldozer and Intel Sandy Bridge features.
Note AMD dropped SSE5 extensions in order to avoid ISA overlap with Intel
AVX instructions. The SSE5 bit was recycled as XOP extended instruction
bit, CVT16 was deprecated in favor of F16C (half-precision float conversion
instructions for AVX), and the remaining FMA4 (4-operand FMA instructions)
gained a separate CPUID bit. Replace non-existent references with today's
CPUID specifications.
