Add support for parsing ARM arithmetic instructions that update or don't update
...
the condition codes. Where the ones that do have an 's' suffix and the ones
that don't don't have the suffix. The trick is if MatchInstructionImpl() fails
we try again after adding a CCOut operand with the correct value and removing
the 's' if present. Four simple test cases added for now, lots more to come.

ARM stm/ldm instructions require more than one register in the register list.

Otherwise, a plain str/ldr should be used instead. Make sure we account for

IntervalMap iterators are heavyweight, so avoid copying them around and use

references instead.
