4%-85.5% regression in media.desktop at 549439:549524

Project Member Reported by chcunningham@chromium.org, Apr 11 2018 
Graphs all seem to return to a previous value after dipping a few days back. Expecting that this is probably a revert of some optimization. Ref graphs held steady.

The CL in question reverts another CL that cause issues and other performance regressions and we have no plans to reland it.
