Cousins may not share style when ascendant affected bits set.

Cousins may not share style when ascendant affected bits set.

childrenOrSiblingsAffectedBy* are set during style matching. Cousins may
not share style in such cases since those affected bits may be set on
uncommon ancestors. Calling setUnique on ComputedStyle in such cases to
avoid style sharing.

This is also true for siblings in which case preceding siblings need to
get the affected bits set when we have adjacent selectors.

Hmm I think this seems right. We should really rethink all this style sharing
stuff, I wonder if we could come up with something simpler.

Lgtm.
