2017-05-10  Carl Love  <cel@us.ibm.com>

   * config/rs6000/rs6000-c: Add support for built-in functions
   vector signed char        vec_neg (vector signed char)
   vector signed short int   vec_neg (vector short int)
   vector signed int         vec_neg (vector signed int)
   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.

gcc/testsuite/ChangeLog:

2017-05-10  Carl Love  <cel@us.ibm.com>
   * gcc.target/powerpc/builtins-3.c: Add tests for the new built-ins to
   to the test suite file.
   * gcc.target/powerpc/builtins-3-p8.c: Add tests for the new built-ins to
   to the test suite file.
