- More refactoring. This gets rid of all of the getOpcode calls.
...
- This change also makes it possible to switch between ARM / Thumb on a
per-function basis.
- Fixed thumb2 routine which expand reg + arbitrary immediate. It was using
using ARM so_imm logic.
- Use movw and movt to do reg + imm when profitable.
- Other code clean ups and minor optimizations.

Let callers decide the sub-register index on the def operand of rematerialized instructions.
...
Avoid remat'ing instructions whose def have sub-register indices for now. It's just really really hard to get all the cases right.
