[PATCH 9/13] rs6000, remove __builtin_vsx_xvnegdp and __builtin_vsx_xvnegsp built-ins

[Carl Love]

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 buit-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.
