For Arm we have seemed to have never added support for llvm.minimum/maximum. (There isn't a good instruction for it, and there isn't any generic expansion, but adding a new type of reduction shouldn't make that any worse).

As I know AArch64 support minimum/maximum intrinsics and they are lowered to native fmin/fmax instructions.
