svenpanne, ptal

Chrome should be migrated by now.

Marja, could you fill the BUG= line with chromium:236173?

[Benedikt Meurer, 2013-09-09 05:30:29]

LGTM.

svenpanne: this would be ready for landing now. Does V8 have try jobs nowadays?
It would be good to run a try job - Chrome *should* be migrated but it's
possible that I missed something, or that somebody introduced a new call to the
default ctor meanwhile.

No, V8 still does not have try jobs. But we have Chromium builders on our
waterfall (using Chromium LKGR + V8 bleeding_edge), so it's perfectly fine to
just land this and see what those bots say.

... now this is ready to land for real (removed 1 more case in Chromium which I
had weirdly missed before).

LGTM (still).
