    {TRAFODION-1562] Index maintenence performance improvements

    Changes to transform an upsert plan into an efficient plan when indexes are present and
allow for rowset type operations.  The plan makes use of existing operators to eliminate duplicates
at the source so we don't need to perform a row at a time check and put operation. The code
is currently turned off with a CD traf_upsert_to_eff_tree.
