    rs6000, Remove redundant vector float/double type conversions
    
    The following built-ins are redundant as they are covered by another
    overloaded built-in.
    
      __builtin_vsx_xvcvspdp covered by vec_double{e,o}
      __builtin_vsx_xvcvdpsp covered by vec_float{e,o}
      __builtin_vsx_xvcvsxwdp covered by vec_double{e,o}
      __builtin_vsx_xvcvuxddp_uns covered by vec_double
    
    Remove the redundant built-ins. They are not documented nor do they have
    test cases.
    
    gcc/ChangeLog:
            * config/rs6000/rs6000-builtins.def (__builtin_vsx_xvcvspdp,
            __builtin_vsx_xvcvdpsp, __builtin_vsx_xvcvsxwdp,
            __builtin_vsx_xvcvuxddp_uns): Remove.
