Additional steps to help ensure that scalar subqueries are only evaluated
once even if they are used in multiple places within the query. This fixes
a performance regression reported on the mailing list and caused by
check-in [531eca6104e41e43] which was a fix for ticket
[787fa716be3a7f650c]. Think of this check-in as an improved fix for
