  Log Message:
  -----------
  [X86] Update SSE/AVX integer MINMAX intrinsics to emit llvm.smax.* etc. (PR46851)

We're now getting close to having the necessary analysis/combines etc. for the new generic llvm smax/smin/umax/umin intrinsics.

This patch updates the SSE/AVX integer MINMAX intrinsics to emit the generic equivalents instead of the icmp+select code pattern.
