Insert dummy ED table entries for pseudo-instructions.
...
The table is indexed by opcode, so simply removing pseudo-instructions
creates a wrong mapping from opcode to table entry.
Add a test case for xorps which has a very high opcode that exposes this
problem.

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.
