895c1e2dee Fix ssat and ssat16 encodings for ARM and Thumb. The bit position value 
must be encoded decremented by one. Only add encoding tests for ssat16
because ssat can't be parsed yet.

584bf7bb03 Add assembly parsing support for "msr" and also fix its encoding. Also add 
testcases for the disassembler to make sure it still works for "msr".

a2b6e4151b Fix encoding and add parsing support for the arm/thumb CPS instruction: 
- Add custom operand matching for imod and iflags.
- Rename SplitMnemonicAndCC to SplitMnemonic since it splits more than CC
  from mnemonic.
- While adding ".w" as an operand, don't change "Head" to avoid passing the
  wrong mnemonic to ParseOperand.
- Add asm parser tests.
- Add disassembler tests just to make sure it can catch all cps versions.

030160073d Fix the encoding of QADD/SUB, QDADD/SUB. While qadd16, qadd8 use "rd, rn, rm", 
qadd and qdadd uses "rd, rm, rn", the same applies to the 'sub' variants. This
is described in ARM manuals and matches the encoding used by the gnu assembler.
