Comment (by Ben Gamari <ben@…>):

 In [changeset:"9498c50ef5af2680305e0aaea6f32439cacc3da0/ghc" 9498c50/ghc]:

 Renamer now preserves location for IEThingWith list items

 Prior to this, in the RenamedSource for

     module Renaming.RenameInExportedType
       (
       MyType (NT)
       ) where

     data MyType = MT Int | NT

 The (NT) was given the location of MyType earlier on the line in the
 export list.

 Also the location was discarded for any field labels, and replaced with
 a `noLoc`.

 Test Plan: ./validate
