Well, I was worried about manual add-remove operands code for every
new instruction we handle. In the ideal world we'd need just to say
"change instruction A to instruction B" and everything else will be
automatic. Surely it's not possible in all cased, however Thumb2 size
reduction pass might be some motivating example.
