This patch add newtype deriving instance declarations to make IntPtr and WordPtr as instance of the Data typeclass.
Thanks for the contribution, @sighingnow! This looks good save for a few minor issues described below.
Please add an entry to libraries/base/changelog.md which describes this change. (Make sure to reference Trac #13115, too.)
Use 22.214.171.124 instead of 126.96.36.199.
(I don't know why Harbormaster is failing to build this, but it's unlikely to be your fault, based on the build output.)
Thanks for your help, @RyanGlScott.
