  Log Message:
  -----------
  [X86] Support -march=x86-64-v[234]

PR47686. These micro-architecture levels are defined in the x86-64 psABI:

https://gitlab.com/x86-psABIs/x86-64-ABI/-/commit/77566eb03bc6a326811cb7e9

GCC 11 will support these levels.

Note, -mtune=x86-64-v[234] are invalid and __builtin_cpu_is cannot be
used on them.
