A significant change to the ORM mechanics involved with both :func:`.orm.with_loader_criteria` as well as single table inheritance, to more aggressively locate WHERE criteria which should be augmented by either the custom criteria or single-table inheritance criteria; SELECT statements that do not include the entity within the columns clause or as an explicit FROM, but still reference the entity within the WHERE clause, are now covered, in particular this will allow subqueries using ``EXISTS (SELECT 1)`` such as those rendered by :meth:`.RelationshipProperty.Comparator.any` and :meth:`.RelationshipProperty.Comparator.has`. Fixes: #13070 Change-Id: I9afb48e1c95b9e61f4e1b6be8e4a634ed5b1df43
