Should the below code just get moved to fetch_source? Or does it rely
on local args which makes that a pain? If it's not too hard, I think
it'd be a lot cleaner / clearer than an extra param here.

Same comment here about moving the sat code into store_dest.

Please comment as to why this is written differently than the
unary/trinary cases. I assume it's for something like DSLT?

I'd group these with the other COMP ones... That's why I had added the
whitespace for INTERP_*.
