Add a fast path for parent selector matching that uses a bloom filter to quickly discard selectors that can't possibly match. Keep in mind that we match using a bloom filter, so we might accidentally include too many selectors when hash/bucket collisions occur. That's not a correctness problem though, because we'll do a real check afterwards. The idea for this change is taken from browsers, in particular WebKit.
