It returns the value that is loaded from the memory and the updates the base
pointer.
void foo (int *restrict ptr, int *output, int loaded_value, int N) {
// This updates loaded_value and updates the ptr to ptr+N

*output = N;
}
The ScheduleDAG creates an ordered memory dependency from the intrinsic_call
to the unrelated store from "output".
