I missed a crucial step in the wiring-in process of `CallStack` in D861,
the bit where you actually wire-in the Name... 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.

Test Plan: `./validate` and `make slowtest TEST=tc198`
