Comment (by Ben Gamari <ben@…>):

 In [changeset:"a7b751db766bd456ace4f76a861e5e8b927d8f17/ghc" a7b751d/ghc]:

 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.

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