Revert of Recompute overflow after transform changes (https://codereview.chromium.org/203463007/)

Reason for revert:
Seems very likely to have broken ChromeOS login page: https://code.google.com/p/chromium/issues/detail?id=365507

Original issue's description:
> Recompute overflow after transform changes
> 
> This CL adds a special code path that is very similar to simplifiedLayout.
> When the only change on an element is the transform, we can do the minimal
> work to recompute the layout overflow without much overhead from layout.
> 
> This is done by adding an overflow recalculation phase after style changes,
> if a RenderObject doesn't need layout and has moved transformed children,
> the special code path will kick in.
