ARM64: add 128-bit MLA operations to the custom selection code.

Without this change, the llvm_unreachable kicked in. The code pattern
being spotted is rather non-canonical for 128-bit MLAs, but it can
happen and there's no point in generating sub-optimal code for it just
because it looks odd.

Should fix PR19332.
