Thumb parsing and encoding support for NOP.
...
The irony is not lost that this is not a completely trivial patchset.

Fix predicates for Thumb co-processor instructions.
...
They're all Thumb2 only, not just some of them. More refactoring cleanup
coming.

ARM asm parser wasn't able to parse a "mov" instruction while in Thumb
...
mode (only the "mov.w" variant). Now, when parsing "mov" in thumb mode,
default to the Thumb 1 versions/encodings.

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.

Add parsing for the Thumb t_addrmode_s4 addressing mode. This can almost
...
certainly be made more generic. But it does allow us to parse something like:
ldr r3, [r2, r4]
correctly in Thumb mode.

Add MC encodings for some Thumb instructions. Test for a few of them. The "bx

lr" instruction cannot be tested just yet. It requires matching a "condition
code", but adding one of those makes things go south quickly...
