style: Shrink CascadeData by turning the bloom filters into hash sets.
We're wasting 1kb there, which is kind of stupid.
The only advantage of using a bloom filter is that memory usage doesn't increase
even if there's a gazillion attribute selectors and such. But:
* For IDs we already have a bunch of data structures for invalidation and such
which key on the id, so the bloom filter would be a very minor thing.
* For attribute selectors we don't have such a data structure, but if people
used a gazillion attribute selectors we should!
