a8307dd1c9 Thumb2 parsing and encoding for LDR(immediate). 
The immediate offset of the non-writeback i8 form (encoding T4) allows
negative offsets only. The positive offset form of the encoding is the
LDRT instruction. Immediate offsets in the range [0,255] use encoding T3
instead.

cfbb3a78db Thumb2 ldm/stm 'db' mnemonics don't have a '.w' suffix. 
There is no 16-bit wide encoding, so the .w suffix isn't needed (indeed, isn't
documented as allowed). Also add the missing '!' token on the _UPD
variant.
