un-wire-in error, undefined, CallStack, and IP
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.
