This depends on the changes in http://codereview.chromium.org/6090002/. I'll need to wait for that to be checked in and then adjust the DEPS roll to at least that revision.

The Chromium changes that this depends on landed as http://crrev.com/70319, so I updated the DEPS roll to that. The patch should build now.
