        >2x speedup on querySelector[All] with :nth-child by removing the collectRulesOnly argument on SelectorChecker.
        With collectRulesOnly set to true (the default) an optimization is turned off, and no callers were intentionally leaving it true.
        querySelector[All] assumed that the default was probably the right way to go, and so ended up being slow.
