9f150bfedf Thumb2 assembly parsing and encoding for LDRD(immediate). 
Refactor operand handling for STRD as well. Tests for that forthcoming.

5ac3aa158b 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.

1aa191032a Thumb2 assembly parsing and encoding for LDR pre-indexed w/ writeback. 
Adjust encoding of writeback load/store instructions to better reflect the
way the operand types are represented.

deb3c78242 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.

20689d28e7 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.

Tweak handling of IT blocks a bit to enable this. The differentiation between
B and Bcc needs special sauce.

as I work my way through the ISA.
