27634	Refactor Query.clone _setup_query logic	Adam Johnson	Adam Johnson	"Currently `Query.clone()` does:

{{{
if hasattr(obj, '_setup_query'):
            obj._setup_query()
}}}

Afaict there's only one subclass of `Query` that has a `_setup_query` method: `UpdateQuery`. The other users were `DateQuerySet` and `DateTimeQuerySet` which got removed in #23867 by Anssi. The call can be pushed down into `UpdateQuery` which already overrides `clone()`."	Cleanup/optimization	closed	Database layer (models, ORM)	1.10	Normal	invalid		me@…	Unreviewed	0	0	0	0	0	0
