I was thinking we could land this without changing the revision to let the ToT
buildbot try it before we roll it in for real.

I'd like to hear what Nico thinks though..

OK, sure, reverted this chunk.

[Nico, 2015/05/29 00:56:21]

Nico is, as often, confused. Wouldn't the ToT buildbot try this with an updated
SUB_REVISION too? It seems strange to me to land this without this bump because
then running package.sh will give you a zip with the same name but different
contents.

Hmm, didn't we just flip this in https://codereview.chromium.org/951983002. I
guess this is the scary part you refer to in the commit message :-)

[eugenis, 2015/05/28 22:37:57]

Exactly. It had no effect until the latest clang roll, and then *boom*
crbug.com/492676.
