This PR changes the fact manager so that, when calling some of the functions in submanagers, passes references to other submanagers if necessary (e.g. to make consistency checks). In particular: - DataSynonymAndIdEquationFacts is passed to the AddFactIdIsIrrelevant function of IrrelevantValueFacts - IrrelevantValueFacts is passed to the AddFact functions of DataSynonymAndIdEquationFacts The IRContext is also passed when necessary and the calls to the corresponding functions in FactManager were updated to be valid and always use an updated context. Fixes #3550.
