  [X86] Convert fmin/fmax _mm_reduce_* intrinsics to emit llvm.reduction intrinsics (PR47506)

This is a follow up of D92940.

We have successfully converted fadd/fmul _mm_reduce_* intrinsics to
llvm.reduction + reassoc flag. We can do the same approach for fmin/fmax
too, i.e. llvm.reduction + nnan flag.
