78affc9ea1 STC2L_POST and STC2L_POST should be handled the same as STCL_POST/LDC_POST for the purposes of decoding all operands except the predicate.

47a0d52b69 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.
