<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Always use rnImplicitBndrs to bring implicit tyvars into scope

This implements a first step towards #16762 by changing the renamer

to always use `rnImplicitBndrs` to bring implicitly bound type

variables into scope. The main change is in `rnFamInstEqn` and

`bindHsQTyVars`, which previously used _ad hoc_ methods of binding

their implicit tyvars.

There are a number of knock-on consequences:

* One of the reasons that `rnFamInstEqn` used an _ad hoc_ binding

  mechanism was to give more precise source locations in

  `-Wunused-type-patterns` warnings. (See

  https://gitlab.haskell.org/ghc/ghc/issues/16762#note_273343 for an

  example of this.) However, these warnings are actually a little

  _too_ precise, since implicitly bound type variables don't have

  exact binding sites like explicitly bound type variables do.

  A similar problem existed for

  "`Different names for the same type variable`" errors involving

  implicit tyvars bound by `bindHsQTyVars`.

  Therefore, we simply accept the less precise (but more accurate)

  source locations from `rnImplicitBndrs` in `rnFamInstEqn` and

  `bindHsQTyVars`. See

  `Note [Source locations for implicitly bound type variables]` in

  `GHC.Rename.HsType` for the full story.

* In order for `rnImplicitBndrs` to work in `rnFamInstEqn`, it needs

  to be able to look up names from the parent class (in the event

  that we are renaming an associated type family instance). As a

  result, `rnImplicitBndrs` now takes an argument of type

  `Maybe assoc`, which is `Just` in the event that a type family

  instance is associated with a class.

* Previously, GHC kept track of three type synonyms for free type

  variables in the renamer: `FreeKiTyVars`, `FreeKiTyVarsDups`

  (which are allowed to contain duplicates)`, and

  `FreeKiTyVarsNoDups` (which contain no duplicates). However, making

  is a distinction between `-Dups` and `-NoDups` is now pointless, as

  all code that returns `FreeKiTyVars{,Dups,NoDups}` will eventually

  end up being passed to `rnImplicitBndrs`, which removes duplicates.

  As a result, I decided to just get rid of `FreeKiTyVarsDups` and

  `FreeKiTyVarsNoDups`, leaving only `FreeKiTyVars`.

* The `bindLRdrNames` and `deleteBys` functions are now dead code, so

  I took the liberty of removing them.
