Given a patch like D129506, using instructions not valid for the current target feature set becomes an error. This fixes an issue in ARMExpandPseudo::ExpandCMP_SWAP where Thumb2 compares were used in Thumb1Only code, such as thumbv8m.baseline targets. Differential Revision: https://reviews.llvm.org/D129695
