drh af3711536b In the query flattener when substituting expression Y in place of expression X, ...

if X is marked has having come from an ON or USING clause of a LEFT JOIN, then
be sure that all subexpressions of Y, not just the root node of Y, are
similarly marked.  Otherwise, if Y is an AND operator, it will be split up
during WHERE clause analysis and the subexpressions will not get the special
treatment needed by LEFT JOIN ON/USING clauses.
Fix for ticket [66e4b0e271c47145].
