Jim Grosbach b908b7af31 Thumb2 parsing and encoding for MOV(immediate). 
Some aliases for MOV(register) also to keep existing T1 tests happy when
run in thumbv7 mode.

Owen Anderson 29cfe6c368 Thumb unconditional branches are allowed in IT blocks, and therefore should have a predicate operand, unlike conditional branches.

Jim Grosbach 3343da5424 Thumb2 assembly parsing and encoding for LDR post-indexed. 
More cleanup of the general indexed addressing T2 instructions. Still more to
do, especially for stores.

Jim Grosbach c086f689f8 Thumb2 assembly parsing and encoding for LDR pre-indexed w/ writeback.

way the operand types are represented.

Jim Grosbach e2d68844bc Thumb2 assembly parsing and encoding for LDR(literal). 
Need branch relocation support to distinguish this encoding from the
16-bit Thumb1 encoding w/o the explicit .w suffix. That comes later, though.

Jim Grosbach a31f223af8 Thumb2 parsing and encoding for LDMIA. 
Choose 32-bit vs. 16-bit encoding when there's no .w suffix in post-processing
as match classes are insufficient to handle the context-sensitiveness of
the writeback operand's legality for the 16-bit encodings.
