[clang][ARM] PACBTI-M assembly support Introduce assembly support for Armv8.1-M PACBTI extension. This is an optional extension in v8.1-M. There are 10 new system registers and 5 new instructions, all predicated on the feature. The attribute for llvm-mc is called "pacbti". For armclang, an architecture extension also called "pacbti" was created. This patch is part of a series that adds support for the PACBTI-M extension of the Armv8.1-M architecture, as detailed here: https://community.arm.com/arm-community-blogs/b/architectures-and-processors-blog/posts/armv8-1-m-pointer-authentication-and-branch-target-identification-extension The PACBTI-M specification can be found in the Armv8-M Architecture Reference Manual: https://developer.arm.com/documentation/ddi0553/latest The following people contributed to this patch: - Victor Campos - Ties Stuij Reviewed By: labrinea Differential Revision: https://reviews.llvm.org/D112420 GitOrigin-RevId: 5cff77c23f43130887b566dd0fe237e1c482e23b
