@MaskRay As discussed in https://github.com/llvm/llvm-project/pull/96160#issuecomment-2468793288, this drops support for ptrauth driver flags, but with an exception for apple targets - to the best of my knowledge, they have use cases for them. Also tagging @ahmedbougacha 

Note: as stated in PR description, the jump table hardening flag (#113149) is left intact since it's not ABI-affecting.
