            * config/rs6000/rs6000.cc (rs6000_file_start): Define just plagen, not
            plagen1, plagen2, or plagen3.
            * config/rs6000/rs6000.md (plagendi3_nora): Generate plagen, not
            plagen1, plagen2, or plagen3.
            (plagendi3): Likewise.
            (plagendi3_noshift): Likewise.
