gcc/testsuite/ChangeLog:

2017-05-16  Carl Love  <cel@us.ibm.com>

	* gcc.target/powerpc/builtins-3.c: New vec_mule, vec_mulo test cases.
	* gcc.target/powerpc/builtins-3-p8.c: Add tests for the new Power 8
	built-ins to the test suite file.  Note, support for mradds exists
	but no test case exists.
	* gcc.target/powerpc/builtins-3-p9.c: Add tests for the new Power 9
	built-ins to the test suite file.
