out to be an effort to convert RIGHT JOIN to LEFT JOIN if the join was on
the first pair of relations, but that messes up the "*" expansion and so won't
work.

make sure all its columns are flushed to NULL when it finishes so that
they appear to be NULL during the RIGHT JOIN post-processing.

the code to compute the unmatched rows for the RIGHT JOIN has not yet been
added, so the result of a RIGHT JOIN is currently the same as an INNER JOIN.

OP_ReleaseReg opcodes. OP_ReleaseReg opcodes are usually only generated for
SQLITE_DEBUG builds and are used to verify that registers are descoped
propertly. But they can get in the way of code understanding when studying
bytecode dumps. So this new optimization setting is provided to
temporarily turn OP_ReleaseReg opcodes off.
