builtins-3.c: Move built-in tests for P8 and P9 to their own test file.

2016-12-07  Carl Love  <cel@us.ibm.com>

	* gcc.target/powerpc/builtins-3.c: Move built-in tests for P8 and
	P9 to their own test file.  This allows precise constraints on the
	effective target and compile options.
	* gcc.target/powerpc/builtins-3-p8.c: New file for the vector
	compare P8 built-in tests.
	* gcc.target/powerpc/builtins-3-p9.c: New file for the vector
	compare P9 built-in tests.
