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. Patch by Petr Pavlu. llvm-svn: 216874
