From 79708b54f2c1043e28d8d2fb46bb9b416b4806d6 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Re-revert "Refactor debuginfo-tests."

This is still breaking greendragon.

At this point I give up until someone can fix the greendragon
bots, and I will probably abandon this effort in favor of using
a private github repository.
