Once we have variable-length instructions, arg2, arg3 should be added here. Then search this file for arg1 and update all those places to work with the other args as well.

I'm not excited about having two variables. In my own 'long-insts' branch I just count oparg, oparg2, oparg3, ...

I think the generator currently emits REG(oparg1). We could change that.

Or we could "#define oparg1 oparg".

I prefer modifying the generator over the macro. REG(oparg1) only occurs once in the generator, explicitly, so it's very easy to change (in fact in ly 'long-instrs' I already changed it.)
