The recently added gcc.target/aarch64/advsimd-intrinsics/vrnd*.c tests cause
failures due to accidentally running on non-ARMv8 hardware - the target check
arm_v8_neon_ok is correct for compilation tests but should be arm_v8_neon_hw
for execution tests.  Fix this and also change arm_v8_neon_hw to return
true for AArch64 so these tests are run on AArch64 too.

    gcc/testsuite/
	* gcc.target/aarch64/advsimd-intrinsics/vrnd.c
	(dg-require-effective-target): Use arm_v8_neon_hw.
	* gcc.target/aarch64/advsimd-intrinsics/vrnda.c
	(dg-require-effective-target): Likewise.
	* gcc.target/aarch64/advsimd-intrinsics/vrndm.c
	(dg-require-effective-target): Likewise.
	* gcc.target/aarch64/advsimd-intrinsics/vrndn.c
	(dg-require-effective-target): Likewise.
	* gcc.target/aarch64/advsimd-intrinsics/vrndp.c
	(dg-require-effective-target): Likewise.
	* gcc.target/aarch64/advsimd-intrinsics/vrndx.c
	(dg-require-effective-target): Likewise.
	* lib/target-supports.exp (check_runtime arm_v8_neon_hw_available):
	Add AArch64 check.
