The first-node and last-node rules in quirks.css don't need to be universal -- we can split them so they have tag selectors for each tag on which we specify a margin in html.css or quirks.css. This will considerably cut the time we spend in SelectorMatches in page loading. (The first-node / last-node check could be pulled out into the SelectorMatchesData construction, but I think we only do 3 checks total per content node right now, so that wouldn't help much. However, the above patch would still help considerably when combined with lazy computation of said values in the SelectorMatchesData as proposed in bug 83834.
