Remove _ => () and replace with "exhaustive" match to avoid future problems?

I'm not actually sure why this is not

_ => {
    intravisit::walk_item(self, &item);
}

If that doesn't break anything, then walk_item can be moved out of the match.

I've made the dead_code lint walk all items by default. I had to exclude ItemKind::ForeignMod, which caused a false negative and explicitly ignore a few Defs, which were now visited, but otherwise there weren't any problems. This should lower the chance an item is accidentally missed now.
