[PATCH] ARM: Improve handling of the Thumb2 M-class MSR instruction

[Petr Pavlu]

Hi,

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.

Thanks,
Petr
