eb4455e4e4 As evidenced by [forum:/forumpost/f3f546025a|forum post f3f546025a], the 
new RIGHT JOIN related restriction on the push-down optimization implemented
by [da3fba18742b6e0b] also needs to apply to the automatic index
(a.k.a. hash-join) optimization and to the Bloom filter optimization.
Computation of the restriction is now
moved into the sqlite3ExprIsSingleTableConstraint() routine.
