Inherited predicates

calls	Holds if `callee` is potentially called from this callable. That is, `callee` is a potential run-time target of a call in the body of this callable.	from Callable
canReturn	Holds if this callable can return expression `e`.	from Callable
canYieldReturn	Holds if this callable can yield return the expression `e`.	from Callable
compiledFromSource	Holds if this element was compiled from source code that is also present in the database. That is, this element corresponds to another element from source.	from NamedElement
controlsBlock	Holds if basic block `controlled` is controlled by this control flow element with conditional value `s`. That is, `controlled` can only be reached from the callable entry point by going via the `s` edge out of some basic block ending with this element.	from ControlFlowElement
