Apply handleVectorReduceIntrinsic() to Intrinsic::aarch64_neon_f{min,max}(mn)?v. Previously, these intrinsics were handled correctly (by maybeHandleSimpleNomemIntrinsic) if each parameter's type was the same as the return type; otherwise, they were handled suboptimally by visitInstruction().
Updates the tests from https://github.com/llvm/llvm-project/pull/125729.
