a RIGHT JOIN in any arm and the subquery is not the first element of the
outer query. Otherwise, prior elements of the outer query will not have
the JT_LTORJ flag set. Fix for the problem reported in
[forum:/forumpost/174afeae5734d42d|forum post 174afeae5734d42d].

in an aggregate query as long as there is no GROUP BY clause. (The GROUP BY
clause will interfere with the operation of the TK_IF_NULL_ROW expression
nodes.)

the outer query holds a GROUP BY, not if the outer query is an aggregate.

RIGHT or LEFT join anywhere in the query. Other RDBMSes prohibit this always,
but SQLite must allow ON clauses to reference tables to their right for legacy
compatibility, unless there is a RIGHT or LEFT join someplace in the query,
in which case there is no legacy to support.

does make the byte code a little easier to read.
