   vector signed long long   vec_neg (vector signed long long)
   vector float              vec_neg (vector float)
   vector double             vec_neg (vector double)
   * config/rs6000/rs6000-builtin.def: Add definitions for NEG function
   overload.
   * config/rs6000/altivec.h: Add define for vec_neg
   * doc/extend.texi: Update the built-in documentation for the
   new built-in functions.
