commit 2a8a787ff73eef6871c8dccb703c95c4fa7377c7
Author: Matthew Cary <mattcary@chromium.org>
Date: Wed May 30 06:30:11 2018

Transform media::SharedMemoryRegion to UnalignedMemoryRegion.

SharedMemoryRegion is a trivial wrapper, as noted in the code, which suggests it
should be removed. In addition, removing it is the first step in the general shared
memory refactoring (see bug).
