[Haskell-cafe] Callstack Implicit Param for Unsafe Prelude Functions

Since the latest base now has a way of getting generating stack traces via
the `CallStack` implicit param, is there any reason not to add that param
to the error messages of unsafe functions in the Prelude ( and even
commonly used modules like Data.Maybe/Data.List)?

The type signature will change but for most users it should be a drop-in
replacement and a great aid to debugging.
