Revert LGTM, though I think the problem is a missing dependency instead
(confirming now).

[Dirk Pranke, 2017-01-26 01:04:48]

A revert of this CL (patchset #1 id:1) has been created in
https://codereview.chromium.org/2654993005/ by dpranke@chromium.org.

The reason for reverting is: This patchset was not to blame for the failure; I
think the failure is a missing dependency as noted in crbug.com/685440. So,
re-landing..
