Clean-up `Data.Fixed`
Clean-up `Data.Fixed`

This gets rid of `-fno-warn-unused-binds` by turning the E* types into
constructor-less data types (as they're used as phantom-types only)

Moreover, this modules uses `AutoDeriveTypeable` so we can drop all those
redundant `deriving (Typeable)` lines as well
