Currently op_wide16 and op_wide32 only apply to the next instruction. But looking at examples, they often seem to be repeated for every instruction in some large sequence.
So I'd like to test having op_toggle8, op_toggle16, op_toggle32, that apply to all instructions until the next toggle. It should both save some memory and ideally some dispatching overhead.
