<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.
