This patch adds code and a test when SQLite generates an 'unknown'
op for a table join in the BEST_INDEX() callback. The Perl code crashed
when such an op was generated for a JOIN criterion by the SQLite engine.
The SQLite engine creates an 'unknown' op on the following SQL
for example:
select r.nodepath
from temp.scan_results r
left join temp.scan_results m
on r.nodepath = m.nodepath+1
where m.nodepath is null
The important part is that the right side of the left join must be
checked for IS NULL.
