Implement Thumb2 ldr.
...
After much back and forth, I decided to deviate from ARM design and split LDR into 4 instructions (r + imm12, r + imm8, r + r << imm12, constantpool). The advantage of this is 1) it follows the latest ARM technical manual, and 2) makes it easier to reduce the width of the instruction later. The down side is this creates more inconsistency between the two sub-targets. We should split ARM LDR instruction in a similar fashion later. I've added a README entry for this.

When possible, use "mvn ra, rb" instead of "eor ra, rb, -1" because mvn has a narrow version and eor(i) does not.

Currently there is a pattern for the thumb-2 MOV 16-bit immediate instruction. That instruction cannot write the flags so it should use T2I instead of T2sI.
...
Also, added a pattern for the thumb-2 MOV of shifted immediate since that can encode immediates not encodable by the 16-bit immediate.
