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.
