Once we have O(1) access to shadowRoot, we can:
1) Easily determine whether we even need to walk anything.
2) Use scopes to check whether we need to adjust relatedTarget. See http://dev.w3.org/2006/xbl2/#the-mouseover-and-mouseout-events for more details.
3) Use scope chain to walk more quickly.

I think we already have O(1) access to shadowRoot. Let me rewrite adjust relatedTarget code.

This isn't causing:
http://samples.msdn.microsoft.com/ietestcenter/domevents/mouseleave.relatedTarget.html
and:
http://samples.msdn.microsoft.com/ietestcenter/domevents/mouseenter.ctrlKey.html
is it?

Nevermind. We don't support those two events. https://bugs.webkit.org/show_bug.cgi?id=18930
