Build on previous patches to successfully distinguish between an M-series and A/R-series MSR and MRS instruction. These take different mask names and have a *slightly* different opcode format. Add decoder and disassembler tests. Improvement on the previous patch - successfully distinguish between valid v6m and v7m masks (one is a subset of the other). The patch had to be edited slightly to apply to ToT. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@140696 91177308-0d34-0410-b5e6-96231b3b80d8
