This led to a nasty bug where GHC thought `CallStack` was not wired-in and tried to fingerprint it, which failed because the defining module was not loaded. But we don't need `CallStack` to be wired-in anymore since `error` and `undefined` no longer need to be wired-in. So we just remove them all. Updates haddock submodule.
