43cade9bb2 ARM allows '' syntax, not just '#imm' for assembly. 
Backwards compatibility with 'gas'. #imm is the preferered and documented
syntax, but lots of existing code uses the '$' prefix, so we should
support it if we can.

044acb8bee ARM assembly parsing for register range syntax for VLD/VST register lists. 
For example,
vld1.f64 {d2-d5}, [r2,:128]!

Should be equivalent to:
vld1.f64 {d2,d3,d4,d5}, [r2,:128]!

It's not documented syntax in the ARM ARM, but it is consistent with what's
accepted for VLDM/VSTM and is unambiguous in meaning, so it's a good thing to
support.

df951fa128 Thumb2 assembly parsing for mul.w in IT block fix. 
When the 3rd operand is not a low-register, and the first two operands are
the same low register, the parser was incorrectly trying to use the 16-bit
instruction encoding.

7e41554aa7 ARM refactor simple immediate asm operand render methods. 
These immediate operands all use the same simple logic for rendering to
MCInst, so have them share the method for doing so.

bc077320e1 ARM vldm and vstm VFP instructions can take a data type suffix. 
It's ignored by the assembler when present, but is legal syntax. Other
instructions have something similar, but for some mnemonics it's
only sometimes not significant, so this quick check in the parser will
need refactored into something more robust soon-ish. This gets some
basics working in the meantime.
