1. The ARM Darwin *r9 call instructions were pseudo-ized recently.
Modify the ARMDisassemblerCore.cpp file to accomodate the change.
2. The disassembler was unnecessarily adding 8 to the sign-extended imm24:
imm32 = SignExtend(imm24:'00', 32); // A8.6.23 BL, BLX (immediate)
// Encoding A1
It has no business doing such. Removed the offending logic.
Add test cases to arm-tests.txt.

The insufficient encoding information of the combined instruction confuses the decoder wrt
UQADD16. Add extra logic to recover from that.

- 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.
