Each pass instrumentation should decide whether or not to run the pass based on whether or not the pass is required or optional. An optional pass may still be run, (which should be the case for the vast majority of instances).
For example, the optnone would only care if a pass is required or not if it sees that a function is marked optnone.
Similarly, opt-bisect would only care if a pass is required if it's hit the bisect limit.
