At the end of the right-hand table loop of a LEFT JOIN that uses an IN

operator in the ON clause, put the OP_IfNoHope operator after the
OP_IfNotOpen operator, not before, to avoid a (harmless) uninitialized
register reference.  Ticket [82b588d342d515d1]

Only choose to scan an IN operator rather than use an index if we have

real STAT1 data to suggest it is advantageous.
