18.1% regression in system_health.memory_mobile at 470537:470574

Project Member Reported by hjd@google.com, May 11 2017 
Kind of seems like the regression is getting worse over time, maybe an infra problem?

Not sure about the webview bots, but the regression appears on a handful of other bots too. I kicked off some more bisects on cc:effective_size where the regression is also cleaner.
