    [TRAFODION-2616] Nested join regression after fix for TRAFODION-2569

    When pushing predicates into a scan node, it is not ok to copy the
    index info of the original scan to the new scan node, since the
    additional predicates may change the set of qualifying indexes.
    
    Also, the method to copy the index info needs to copy the set of
    computed predicates, since these are computed in the addIndexInfo()
    method.
