Fix a NEON disassembly case that was broken in the recent refactorings. As more of this code gets refactored, a lot of these manual decoding hooks should get smaller and/or go away entirely.

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.

invalid-LDR_PRE-arm.txt was already passing, but for the wrong reasons. We were failing to specify enough fixed bits of LDR_PRE/LDRB_PRE, resulting in decoding conflicts. Separate them into immediate vs. register versions, allowing us to specify the necessary fixed bits. This in turn results in the test being decoded properly, and being rejected as UNPREDICTABLE rather than a hard failure.
