The llvm test look OK if you wanted to push those separately.

if (MtuneLowerCase == "cyclone" ||
StringRef(MtuneLowerCase).starts_with("apple")) {
Features.push_back("+zcm");
Features.push_back("+zcm-gpr64");

I don't think this code should be here, as it should be automatic from the cpu tuning features. Can it be removed?

Yes, I plan to fix that in a future patch. This is just a quick fix.

This change removes unnecessary tune args to the AArch64 backend. The AArch64 backend automatically handles `tune-cpu` and adds the necessary features based on the models from TableGen.

It follows this fix: llvm#146260 where updating a subtarget feature didn't fail the frontend test because both the toolchain and the test suffered from a coordinated error.
