drh	c49de5d98c	Make sure the IS NULL optimization introduced by check-in (3494) correctly ... handles a LEFT JOIN where the a term from the right table of the join uses an IS NULL constraint. Ticket #2177. This check-in also adds the new test cases that were suppose to have been added with (3494) but which were mistakenly omitted.
