    rs6000, remove __builtin_vsx_xvnegdp and __builtin_vsx_xvnegsp built-ins
    
    The undocumented __builtin_vsx_xvnegdp and __builtin_vsx_xvnegsp are
    redundant.  The overloaded vec_neg built-in provides the same
    functionality.  The two built-ins are not documented nor are there any
    test cases for them.
    
    Remove the definitions so users will use the overloaded vec_neg built-in
    which is documented in the PVIPR.
    
    gcc/ChangeLog:
            * config/rs6000/rs6000-builtins.def (__builtin_vsx_xvnegdp,
            __builtin_vsx_xvnegsp): Remove built-in definitions.
