I think not just aarch64, doesn't it need some effective target that
the HW on which it is tested is ARM v8.2-a compatible plus that binutils
can assemble v8.2-a instructions?
Sure, it can be done in gcc.dg/vect too if those effective targets
aren't defined in aarch64.exp. But probably needs dg-additional-options
there instead of dg-options.
