Committed patchset #1 (id:1) manually as
6a85b3b95353c94da606f9f689b962cb17b21041 (presubmit successful).

[Yuta Kitamura, 2016-06-20 10:25:49]

NOT LGTM

Please don't revert this. This patch is extremely costly
to land.

[Yuta Kitamura, 2016-06-20 10:30:48]

I'm going to revert this revert since it's unacceptable to
revert this giant patch just for another patch's regression.

If you are not sure how to revert a CL without reverting this
one, please let me know. I can do that for you.
