    JOIN::cur_dups_producing_tables was not maintained correctly in
    the cases of greedy optimization (search_depth < n_tables).
    
    Moved it to POSITION structure where it will be maintained automatically.
    
    Removed POSITION::prefix_dups_producing_tables since its value can now
    be calculated.
