<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Simplify bindLHsTyVarBndrs and bindHsQTyVars

Both `bindLHsTyVarBndrs` and `bindHsQTyVars` take two separate

`Maybe` arguments, which I find terribly confusing. Thankfully, it's

possible to remove one `Maybe` argument from each of these functions,

which this patch accomplishes:

* `bindHsQTyVars` takes a `Maybe SDoc` argument, which is `Just` if

  GHC should warn about any of the quantified type variables going

  unused. However, every call site uses `Nothing` in practice. This

  makes sense, since it doesn't really make sense to warn about

  unused type variables bound by an `LHsQTyVars`. For instance, you

  wouldn't warn about the `a` in `data Proxy a = Proxy` going unused.

  As a result, I simply remove this `Maybe SDoc` argument altogether.

* `bindLHsTyVarBndrs` also takes a `Maybe SDoc` argument for the same

  reasons that `bindHsQTyVars` took one. To make things more

  confusing, however, `bindLHsTyVarBndrs` also takes a separate

  `HsDocContext` argument, which is pretty-printed (to an `SDoc`) in

  warnings and error messages.

  In practice, the `Maybe SDoc` and the `HsDocContext` often contain

  the same text. See the call sites for `bindLHsTyVarBndrs` in

  `rnFamInstEqn` and `rnConDecl`, for instance. There are only a

  handful of call sites where the text differs between the

  `Maybe SDoc` and `HsDocContext` arguments:

  * In `rnHsRuleDecl`, where the `Maybe SDoc` says "`In the rule`"

    and the `HsDocContext` says "`In the transformation rule`".

  * In `rnHsTyKi`/`rn_ty`, where the `Maybe SDoc` says

    "`In the type`" but the `HsDocContext` is inhereted from the

    surrounding context (e.g., if `rnHsTyKi` were called on a

    top-level type signature, the `HsDocContext` would be

    "`In the type signature`" instead)

  In both cases, warnings/error messages arguably _improve_ by

  unifying making the `Maybe SDoc`'s text match that of the

  `HsDocContext`. As a result, I decided to remove the `Maybe SDoc`

  argument to `bindLHsTyVarBndrs` entirely and simply reuse the text

  from the `HsDocContext`. (I decided to change the phrase

  "transformation rule" to "rewrite rule" while I was in the area.)

  The `Maybe SDoc` argument has one other purpose: signaling when to

  emit "`Unused quantified type variable`" warnings. To recover this

  functionality, I replaced the `Maybe SDoc` argument with a

  boolean-like `WarnUnusedForalls` argument. The only

  `bindLHsTyVarBndrs` call site that chooses _not_ to emit these

  warnings in `bindHsQTyVars`.
