Collects passes and constraints. This defines the pass schedule, manages pass constraints and pass execution. Args: passes (Optional[List[Callable]]): list of passes. A pass is a callable which modifies an object and returns modified object constraint (Optional[List[Callable]]): list of constraints. A constraint is a callable which takes two passes (A, B) and returns True if A depends on B and False otherwise.
