Rename target descriptions to reflect actual content of description.

To better reflect the actual feature set covered by the IA target
descriptions, the existing descriptions are renamed. Each feature of
the extended state is added to the name of a description or xstate mask
starting from AVX.
For example, amd64-mpx-avx512-linux becomes amd64-avx-mpx-avx512-linux,
while amd64-avx-linux remains unchanged.
Likewise, the corresponding xstate masks are changed, e.g. from
X86_XSTATE_MPX_AVX512_MASK to X86_XSTATE_AVX_MPX_AVX512_MASK.
