This broke fast/regions/auto-size/autoheight-two-pass-layout-complex-002.html on WK1, not sure why EWS didn't notice. Maybe it fails when run with other tests, but succeeeds alone?

r181909: <http://trac.webkit.org/changeset/181909> made it better for WK2 on Yosemite, but the test is still failing on WK1 Yosemite, and on Mavericks bots.
As it still fails and Dave is not around, rolling out.
Re-opened since this is blocked by bug 143034
