Shouldn't this also include other flags that imply AVX?
Like CpuFMA|CpuFMA4|CpuXOP ?

Shouldn't CPU_ANY_SSE_FLAGS include also all the new CPU_ANY_AVX_FLAGS?

What about CPU_F16C_FLAGS and CpuF16C?  E.g. in GCC -mf16c implies
-mavx and -mno-avx implies -mno-f16c.  So shouldn't CPU_F16C_FLAGS also
include CpuMMX|CpuSSE|CpuSSE2|CpuSSE3|CpuSSSE3|CpuSSE4_1|CpuSSE4_2|CpuAVX
and CPU_ANY_AVX_FLAGS include CpuF16C and similarly CPU_ANY_SSE_FLAGS?
