PTAL.

I'm generating the revert for mstensho@ as he's out of the office. Please give
this a read over. There was a conflict in TestExpectations which I rebuilt by
and, and a conflict in LayoutObject due to LayoutStyle -> ComputedStyle.

Could you add a link to the original CL this is based on in the description?

Reverting is the right thing to do, I would like us to look into fixing the
issues and getting this re-landed in the very near term though.
