Jim Grosbach b7fa2c0a53 Thumb parsing diagnostics for low-reg requirements on ADD and MOV.

Jim Grosbach 3e941aee69 ARM thumb assembly parsing for arithmetic flag setting instructions. 
Thumb one requires that many arithmetic instruction forms have an 'S'
suffix. For Thumb2, the whether the suffix is required or precluded depends
on whether the instruction is in an IT block. Use target parser predicates
to check for these sorts of context-sensitive constraints.
