            * config/rs6000/rs6000-builtin.def: (BU_P10V_VSX_1) New builtin
            macro expansion.
            (XVCVBF16SPN, XVCVSPBF16): Replace macro expansion BU_VSX_1 with
            BU_P10V_VSX_1.
            * config/rs6000/rs6000-call.c: (VSX_BUILTIN_XVCVSPBF16,
            VSX_BUILTIN_XVCVBF16SPN): Replace with P10V_BUILTIN_XVCVSPBF16,
            P10V_BUILTIN_XVCVBF16SPN respectively.
