Miscellaneous improvements to `Convert` (#1020)
Now that Haddock is moving towards working entirely over `.hi` and `.hie` files,
all declarations and types are going to be synthesized via the `Convert` module.
In preparation for this change, here are a bunch of fixes to this module:
* Add kind annotations to type variables in `forall`'s whose kind is not `Type`,
unless the kind can be inferred from some later use of the variable. See
`implicitForAll` and `noKindTyVars` in particular if you wish to dive into this.
* Properly detect `HsQualTy` in `synifyType`. This is done by following suit with
what GHC's `toIfaceTypeX` does and checking the first argument of
`FunTy{} :: Type` to see if it classified as a given/wanted in the typechecker
(see `isPredTy`).
* Beef up the logic around figuring out when an explicit `forall` is needed. This
includes: observing if any of the type variables will need kind signatures, if the
inferred type variable order _without_ a forall will still match the one GHC
claims, and some other small things.
* Add some (not yet used) functionality for default levity polymorphic type
signatures. This functionality similar to `fprint-explicit-runtime-reps`.
Couple other smaller fixes only worth mentioning:
* Show the family result signature only when it isn't `Type`
* Fix rendering of implicit parameters in the LaTeX and Hoogle backends
* Better handling of the return kind of polykinded H98 data declarations
* Class decls produced by `tyThingToLHsDecl` now contain associated type
defaults and default method signatures when appropriate
* Filter out more `forall`'s in pattern synonyms
