    Move CallStack back to base
    
    CallStack requires tuples, instances of which are defined in GHC.Tuple.
    Unfortunately the change made in D757 to the `Typeable` deriving
    mechanism means that `GHC.Tuple` must import `GHC.Types` for types
    necessary to generate type representations.  This results in a cycle.
    
    Test Plan: Validate
