2.9% regression in smoothness.tough_canvas_cases at 442247:442296

Project Member Reported by benjhayden@chromium.org, Jan 12 2017 
Interestingly, this commit range doesn't overlap with the other recent frame_times regression.

Bisect failed: http://build.chromium.org/p/tryserver.chromium.perf/builders/winx64_10_perf_bisect/builds/832
Failure reason: the build has failed.
Additional errors:
Bisect aborted early for lack of confidence.
Either of the initial "good" or "bad" revisions failed to be tested or built.

Bisect has failed.

Also from graph looks like regression has recovered. Closing the bug.
