commit 9e862765ffe161da8a4fd9cd67b0a600874feaa9
Author: Ryan Scott <ryan.gl.scott at gmail.com>
Date:   Fri Sep 30 20:15:25 2016 -0400

    Implement deriving strategies
    
    Allows users to explicitly request which approach to `deriving` to use
    via keywords, e.g.,
    
    ```
    newtype Foo = Foo Bar
      deriving Eq
      deriving stock    Ord
      deriving newtype Show
    ```
    
    Fixes #10598. Updates haddock submodule.
    
    Test Plan: ./validate
