Do not mark the ephemeral tables used to hold the RHS of IN clauses as

Do not mark the ephemeral tables used to hold the RHS of IN clauses as
unordered because the NGQP will use those ephemeral tables to help order the
output.  This is not an issue for standard SQLite since ephemeral tables
there are always ordered, regardless of the hint.  It only affects systems
that substitute an alternative storage engine.
