Summary: It is important to emit HINT instructions instead of PAC ones when PAC is disabled. This allows compatibility with other assemblers (e.g. GAS). This was implemented in commit da33762de853. Still, developers of assembly code will want to write code that is compatible with both pre- and post-PAC CPUs. They could use HINT mnemonics, but the new mnemonics are a lot more readable (e.g. paciaz instead of hint #24), and they will result in the same encodings. So, while LLVM should not *emit* the new mnemonics when PAC is disabled, this patch will at least make LLVM *accept* assembly code that uses them.
