Doesn't this warning trigger even if arm_neon.h is nowhere to be
found? That seems a bit broad, the GNU vector extensions are useful in
their own right, and I'm not sure we should be effectively deprecating
them on ARM.

Unfortunately, I've got no ideas on how to only give a message when
it's relevant. I don't really do much on clang either.

Other than that, you need a Triple::aarch64 check too.

Cheers.

Tim.
