<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Use HsForAllTelescope to avoid inferred, visible foralls
Currently, `HsForAllTy` permits the combination of `ForallVis` and
`Inferred`, but you can't actually typecheck code that uses it
(e.g., `forall {a} ->`). This patch refactors `HsForAllTy` to use a
new `HsForAllTelescope` data type that makes a type-level distinction
between visible and invisible `forall`s such that visible `forall`s
do not track `Specificity`. That part of the patch is actually quite
small; the rest is simply changing consumers of `HsType` to
accommodate this new type.
Fixes #18235. Bumps the `haddock` submodule.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">FFI: Fix pass small ints in foreign call wrappers
The Haskell calling convention requires integer parameters smaller
than wordsize to be promoted to wordsize (where the upper bits are
don't care). To access such small integer parameter read a word from
the parameter array and then cast that word to the small integer
target type.
Fixes #15933
