Darwin, ppc, backport fixes to exclude Darwin from VSX, power8 & 9.

This fixes a large number of test fails when we build PPC Darwin
with an LLVM-based assembler (that recognises the insns).

The patch augments the tests for feature support for VSX,
power8 and power9 to exclude Darwin even if the assembler can
handle the instructions.

	Backport from mainline.

	* lib/target-supports.exp
	(check_effective_target_powerpc_p8vector_ok): No support for Darwin.
	(check_effective_target_powerpc_p9vector_ok): Likewise.
	(check_effective_target_powerpc_float128_sw_ok): Likewise.
	(check_effective_target_powerpc_float128_hw_ok): Likewise.
	(check_effective_target_powerpc_vsx_ok): Likewise.
	* gcc.target/powerpc/bfp/bfp.exp: Don't try to run this for Darwin.
	* gcc.target/powerpc/dfp/dfp.exp: Likewise.
