AANonNull is now the first AA that is always queried via the new APIs and not created manually. Others will follow shortly to avoid trivial AAs whenever possible. This commit introduced some helper logic that will make it simpler to port the next one. It also untangles AADereferenceable and AANonNull such that the former does not keep a handle on the latter. Finally, we stop deducing `nonnull` for `undef`, which was incorrect.
