This MR was triggered by #24868, but I found a number of bugs
and infelicities in type-tidying as I went along. Highlights:
* Fix to #24868 is in GHC.Tc.Errors.report_unsolved: avoid
using the OccNames of /bound/ variables when tidying /free/
variables; see the call to `tidyAvoiding`. That avoid the
gratuitous renaming which was the cause of #24868. See
Note [tidyAvoiding] in GHC.Core.TyCo.Tidy
* Refactor and document the tidying of open types.
See GHC.Core.TyCo.Tidy
Note [Tidying open types]
Note [Tidying is idempotent]
* Tidy the coercion variable in HoleCo. That's important so
that tidied types have tidied kinds.
* Some small renaming to make things consistent. In particular
the "X" forms return a new TidyEnv. E.g.
tidyOpenType :: TidyEnv -> Type -> Type
tidyOpenTypeX :: TidyEnv -> Type -> (TidyEnv, Type)
