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

With #9242 the `OverlappingInstances` extension got deprecated, this
commit adapts the only two remaining places in `base` where it was still
used.

Starting with this commit, the `Typeable (s t)` instance (which seemingly
was the motivation for using `OverlappingInstances` in the first place
when `Typeable` was neither polykinded nor auto-derived-only, see also
commit ce3fd0e0 which introduced
overlapping instances) does no longer allow overlapping instances, and
there doesn't seem to be any good reason to keep allowing overlapping
instance now.

This also removes redundant `LANGUAGE`/`OPTIONS_GHC` pragmas from
`Data.Typeable` and refactors the language pragmas into more uniform
single-line pragmas.

Summary:
swprintf has different signatures in mingw32, where it does not include the
buffer size, and in mingw-w64, where it does. That of course breaks the code
as mingw-w64 treats the pointer to the format string as a size_t.

snwprintf is available in both environments and is consistent, so use that
instead.

Rewrite `take` more aggressively for fusion. Add some more explicit
strictness to `unsafeTake` and `unsafeDrop` that seems to help code size and
allocation just a drop in some nofib tests. They were not previously
strict in their numerical arguments, but always called in contexts where
those had been forced; it didn't make a difference in simple test cases,
but made a small difference for nofib. See #9740.

Rearrange some oddly placed code.

Modify `take` to make the fold unconditionally strict in the passed

This gets rid of all hand-unboxing in `GHC.List` and moves `Foldable`
requirements from `Data.OldList` into `GHC.List` (preparatory work for
addressing #9716).  Specifically, this moves the definition of
`maximum`, `minimum`, `foldl'`, `foldl1`, `foldl1'`, `sum`, and
`product` into `GHC.List` (which now needs to import `GHC.Num`)

Make `take`, `drop`, `length`, and `!!` generally saner (see also #9510)

Performance overall seems minimally affected. Some things go up; some
things go down; nothing moves horribly much. The code is much easier to
read.

When investigating a case of unexpected Call Arity failure I noticed
that iterateFB would not inline as far as desired, as it is recursive.

This patch makes it non-recursive (with a local go), which seem so do
great good.

And make normalise_fun polyvariadic. After all, this is untyped code, so
lets make use of it :-)

This is more readable than nesting `two_normalisers()`-invocations

Integer is currently a wired-in type for integer-gmp. This requires
replicating its inner structure in `TysWiredIn`, which makes it much
harder to change Integer to a more complex representation (as
e.g. needed for implementing #9281)

This commit stops `Integer` being a wired-in type, and makes it
known-key type instead, thereby simplifying code notably.
