Jim Grosbach 2f2e3c4737 ARM VLD parsing and encoding.
Next step in the ongoing saga of NEON load/store assmebly parsing. Handle
VLD1 instructions that take a two-register register list.

Adjust the instruction definitions to only have the single encoded register
as an operand. The super-register from the pseudo is kept as an implicit def,
so passes which come after pseudo-expansion still know that the instruction
defines the other subregs.

Owen Anderson 03a173eb71 Don't automatically set the "fc" bits on MSR instructions if the user didn't ask for them. This is a divergence from gas' behavior, but it is correct per the documentation and allows us to forge ahead with roundtrip testing.

Jim Grosbach 741cd73aab ARM NEON "vmov.i8" immediate assembly parsing and encoding.
NEON immediates are "interesting". Start of the work to handle parsing them
in an 'as' compatible manner. Getting the matcher to play nicely with
these and the floating point immediates from VFP is an extra fun wrinkle.

not, and adjust the parser accordingly.

Jim Grosbach b8d9f51e4c Improve ARM assembly parser diagnostic for unexpected tokens.
Consider:
  mov r8, r11 fred

Previously, we issued the not very informative:
x.s:6:1: error: unexpected token in argument list

^

Now we generate:
x.s:5:14: error: unexpected token in argument list
  mov r8, r11 fred
              ^

James Molloy 21efa7d6e1 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.
