  Log Message:
  -----------
  [CIR] Implement __builtin_cpu_supports, _init, and _is (#212900)

These are pretty trivial checks to a builtin variable, so this
implements it for x86, as this shows up in self-build. The tests are
pulled from classic-codegen and shows that we do the reasonable thing
for each of them.
