> Dave, can you check this with the nesting PLT?

Hyatt mentioned on IRC a page that was "getting pwned by absolutePosition" and
that computeAbsoluteRepaintRect was the "top offender for deeply nested
inlines" (after applying some of his optimizations).

I suppose it was in reference to non-cached pages, where image loading causes a
ton of incremental relayout. In fact, for initial layout this patch may turn
out to be bad, since it pushes state even if !checkForRepaint. Perhaps that can
be avoided.
