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.

Jim Grosbach a0d34d3b5e Thumb2 parsing and encoding of B instruction. 
Tweak handling of IT blocks a bit to enable this. The differentiation between
B and Bcc needs special sauce.

For other shift and rotate instructions, too. Tests for those forthcoming
as I work my way through the ISA.

Also add instruction aliases for non-.w versions of SBC since they're the
same.
