bc71b1d453 Only eliminate inner loops of a JOIN if they are the RHS of a LEFT JOIN 
and if they give no more than a single result.  This appears to give correct
answers in all cases.

fd636c7541 Attempt to disable inner loops of a join that do not generate output. 
This does not work, since the inner loops might run zero times and thus
inhibit all output.  Needs to be enhanced to work only for LEFT JOINs
or when we know that the inner loop will always run at least once.
