msw@, please take a look. Also let me know which of the tests tagged with
TODO(msw): ... crbug.com/584038 should be re-enabled.

[msw, 2016-06-22 19:57:47]

lgtm; I can try to re-enable the crbug.com/584038 tests incrementally... I have
no clue what has changed since I initially brought up the suite.

James, can you please take a look?

Mike, please wait until my other CL lands
(https://chromiumcodereview.appspot.com/2067223003/) before re-enabling any of
those tests (I expect there to be some merge conflicts)
