Check in a patch that has already been code reviewed by Owen that I'd forgotten to commit. 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. llvm-svn: 140696

msr apsr, r0
Fix the encoding of the armv7m (MClass) for MSR APSR writes which was missing the 0b10 mask encoding bits. Make MSR APSR writes without a _<bits> qualifier an alias for MSR APSR_nzcvq even though ARM as deprecated it use. Also add support for suffixes (_nzcvq, _g, _nzcvqg) for APSR versions. Some FIXMEs in the code for better error checking when versions shouldn't be used. rdar://11457025 llvm-svn: 157019
