Fixed an ARM disassembler bug where it does not handle STRi12 correctly because an extra
...
register operand was erroneously added. Remove an incorrect assert which triggers the bug.

LLVM combines the offset mode of A8.6.199 A1 & A2 into STRBT.
...
The insufficient encoding information of the combined instruction confuses the decoder wrt
UQADD16. Add extra logic to recover from that.

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.

Revert both r121082 (which broke a bunch of constant pool stuff) and r125074 (which worked around it). This should get us back to the old, correct behavior, though it will make the integrated assembler unhappy for the time being.
