f-moves : makes sure to prepare a function header s-moves : adjust the stack to the target of the move
This looks minimally, but the f-move and s-move variants together with ordinary moves is a flavor for every
value producing instruction, in some way we would need to add flags to many of the instructions or triple the number of them. I need to play with this further to understand how to solve this issue.
Also another kind of difficulty will arise, many instructions only take a
value of 256 register positions, we would somehow need to handle the larger instructions by moving things and this is complicated. Don't know what to do about this yet either.
