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.

a8307dd1c9 Thumb2 parsing and encoding for LDR(immediate). 
The immediate offset of the non-writeback i8 form (encoding T4) allows
negative offsets only. The positive offset form of the encoding is the
LDRT instruction. Immediate offsets in the range [0,255] use encoding T3
instead.

76ecc3d35b Thumb2 parsing and encoding for LDMIA. 
Choose 32-bit vs. 16-bit encoding when there's no .w suffix in post-processing
as match classes are insufficient to handle the context-sensitiveness of
the writeback operand's legality for the 16-bit encodings.

98447daa95 ARM .code directive should always go to the streamer. 
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).

handle encodings T1 and T2 when in Thumb2 mode.
