If possible, I'd prefer for the option to be "-mtp=", to match the option accepted by clang and GCC for AArch32.

No, there's no existing option as far as I'm aware.

I'm happy to use `-mtp=`, as long as it is ok for it to remain in `Group<m_arm_Features_Group>` and to list values for both AArch32 and AArch64. It looks like these things only affect value completion and documentation; is that correct?
