UMA: Time from OnReceiveResponse to OnStartLoadingResponseBody in renderer.
This adds a histogram to the renderer similar to the browser one added
in r758112.
Testing locally there is up to ~1 second of delay because of main thread
contention (JavaScript, layout, etc). Getting real-world data may be
useful.
