When multiple constraints need to be evaluated for a row, do any constraints that involve correlated subqueries last. Hence, the priority is index-covered constraints first, correlated subquery constraints last, and all others in the middle. This is a follow-on and improvement to the push-down optimization of check-in [d7bb79ed]. check-in: c4cb90487f user: drh tags: trunk
