We were failing to account for the cc_pend_sc flag in this
important function, with the result that we expanded superclasses
forever.
Fixes #22516.

As #22521 showed, in tcPatSynSig we make a "fake type" to
kind-generalise; and that type has unzonked type variables in it. So
we must not use `mkFunTy` (which checks FunTy's invariants) via
`mkPhiTy` when building this type. Instead we need to use
`mkNakedFunTy`.
Easy fix.

Unboxed sums might store a Int8# value as Int64#. This patch
makes sure we keep track of the actual value type.

This change would allow `Void` to be used deeper in module graph.
For example exported from `Prelude` (though that might be already
possible).
Also this change includes a change `stimes @Void _ x = x`,
https://github.com/haskell/core-libraries-committee/issues/95
While the above is not required, maintaining old stimes behavior
would be tricky as `GHC.Base` doesn't know about `Num` or `Integral`,
which would require more hs-boot files.
