e90ac9bce9 ARM NEON VST2 assembly parsing and encoding. 
Work in progress. Parsing for non-writeback, single spaced register lists
works now. The rest have the representations better factored, but still
need more to be able to parse properly.

has any correctly sized type suffix.

81550dc0a8 Fix the issue that r143552 was trying to address the _right_ way. One-register lists are legal on LDM/STM instructions, but we should not print the PUSH/POP aliases when they appear. This fixes round tripping on this instruction.

a0ed0c0fcd 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.

acad68da50 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.
