constraint.  Fix for the problem identified by

433a3e935d Back out the EXISTS-to-IN optimization. It slows things down rather than 
speeds them up depending on the query.  And (see
[forum:/forumpost/8692d94725|forum post 8692d94725]) it sometimes results in
an incorrect answer.  We may come back and revisit this optimization later,
but for now it seems best just to disable it.
