This reverts commit e038bde2679bbd200086c25ab43090ad3b8b25a3, reapplying
b2959e9f1a57279506ca46d56bc424fd7fa6b62a.

Note that the commit now being reverted is technically correct; the only
reason we're reverting it is because it should not have been pushed past
the Soft Feature Freeze for the edk2-stable201811 tag.
