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.

Even if there's no mode switch performed, the .code directive should still
be sent to the output streamer. Otherwise, for example, an output asm stream
is not equivalent to the input stream which generated it (a dependency on
the input target triple arm vs. thumb is introduced which was not originally
there).
