Thumb2 M-class MSR instruction support changes This patch implements a few changes related to the Thumb2 M-class MSR instruction: * better handling of unpredictable encodings, * recognition of the _g and _nzcvqg variants by the asm parser only if the DSP extension is available, preferred output of MSR APSR moves with the _<bits> suffix for v7-M.

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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@140696 91177308-0d34-0410-b5e6-96231b3b80d8

@ Check that the assembler can handle the documented syntax from the ARM ARM.

@ These tests test instruction encodings specific to v6m & v7m (FeatureMClass).

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 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157019 91177308-0d34-0410-b5e6-96231b3b80d8
