5fe93eee - `AbstractInterpreter`: allow overloading `merge_effects!` (#46559)

`AbstractInterpreter`: allow overloading `merge_effects!` (#46559) This allows external `AbstractInterpreter`s to observe effects computed for each statement (as like `add_remark!`) and show more fine-grained effects information, e.g. in Cthulhu's code view.
