Update x86 CPU_XXX_FLAGS handling

Support defining CPU_XXX_FLAGS with other CPU_XXX_FLAGS.  Update
CPU_XXX_FLAGS to enable more bits like x87 and SYSCALL.  Don't enable
MMX when enabling SSE, AVX or AVX512.  Don't disable AVX nor AVX512 when
disabling SSE.  Don't disable AVX512 when disabling AVX.  Disable F16C,
FMA, FMA4 and XOP when disabling AVX.  Add 87, no287, no387, no687,
nosse2, nosse3, nossse3, nosse4.1, nosse4.2, nosse4 and noavx2 directives
to x86 assembler.

TODO: Add more .noXXX, like .noavx512f, directives to x86 assembler.
