Is the user of the Attributor a module pass or not.
This determines what IR we can look at and modify. If it is a module pass we might deduce facts outside the initial function set and modify functions outside that set, but only as part of the optimization of the functions in the initial function set. For CGSCC passes we can look at the IR of the module slice but never run any deduction, or perform any modification, outside the initial function set (which we assume is the SCC).
