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.

where the statistics deceive the query planner into using a scan when
an indexed lookup would be better. This check-in changes the code
generation to do the IN-scan using a new OP_SeekScan opcode. That new
opcode is designed to abandon the scan and fall back to a seek if
it doesn't find a match quickly enough. For this work-in-progress check-in,
OP_SeekScan is still a no-op and OP_SeekGE still ends up doing all the work.
