[PATCH 5/6] rs6000: New testsuite selectors


This introduces four new selectors for use with Power testcases:
longdouble64, ppc_float128, ppc_float128_insns, powerpc_vsx.


2018-07-16  Segher Boessenkool  <segher@kernel.crashing.org>

	* lib/target-supports.exp (check_effective_target_longdouble64,
	check_effective_target_ppc_float128,
	check_effective_target_ppc_float128_insns,
	check_effective_target_powerpc_vsx): New.
