rs6000: powerpc_future_ok and powerpc_future_hw

Dejagnu targets for these.

2020-05-11  Kelvin Nilsen  <kelvin@gcc.gnu.org>

	* gcc.target/powerpc/dg-future-0.c: New.
	* gcc.target/powerpc/dg-future-1.c: New.
	* lib/target-supports.exp (check_powerpc_future_hw_available):
	Replace -mfuture with -mcpu=future.
	(check_effective_target_powerpc_future_ok): Likewise.
	(is-effective-target): Add powerpc_future_hw.
