There are two forms of MSP430X extended shift instructions:

- "RxxM": RRAM, RRUM, RLAM, RRCM e.g. rram #3, r12
- "RxxX": RRAX, RRUX, RLAX, RRCX e.g. rrax r12

RxxX shifts do not specify the shift count in the instruction. The shift
count is set separately by setting the repetition count in the extension
word that precedes the instruction. This support will be added in a
separate patch.
