base: Manually unlit .lhs into .hs modules

This commit mostly converts literate comments into ordinary
Haskell comments or sometimes even Haddock comments, while also
removing literate comments in a few cases where they don't make
much sense anymore.

Moreover, in a few cases trailing whitespaces were removed as well.

+This SOURCE-imported hs-boot module cuts a big dependency loop:
+
+         GHC.Exception
+imports  Data.Maybe
+imports  GHC.Base
+imports  GHC.Err
+imports  {-# SOURCE #-} GHC.Exception
+
+More dramatically
+
+         GHC.Exception
+imports  Data.Typeable
+imports  Data.Typeable.Internals
+imports  GHC.Arr (fingerprint representation etc)
+imports  GHC.Real
+imports  {-# SOURCE #-} GHC.Exception
+
+However, GHC.Exceptions loop-breaking exports are all nice,
+well-behaved, non-bottom values.  The clients use 'raise#'
+to get a visibly-bottom value.
