Expand joins when calculating PostgreSQL "WITH FOR UPDATE OF"
Modified the :paramref:`.Select.with_for_update.of` parameter so that if a
join or other composed selectable is passed, the individual :class:`.Table`
objects will be filtered from it, allowing one to pass a join() object to
the parameter, as occurs normally when using joined table inheritance with
the ORM. Pull request courtesy Raymond Lu.
