@Szelethus, could you double-check that there's no way to tweak some graph traits (or something like that) in order to filter out null-successors specifically for Clang CFG? I don't immediately see a way to do that, but i might have missed something. Given that `ChildrenGetter<Direction>::Get` returns a `SmallVector`, it shouldn't be that impossible.

Otherwise i hope an extra defensive check wouldn't hurt.
