* Simplify LikeFilter implementation of getBitmapIndex, estimateSelectivity.
LikeFilter:
- Reduce code duplication, and simplify methods, at the cost of incurring an extra box
of ImmutableBitmap into a SingletonImmutableList. I think this is fine, since this
should be cheap and the code path is not hot (just once per filter).
Filters:
- Make estimateSelectivity public since it seems intended that they be used by Filter
implementations, and Filters from extensions may want to use them too. Removed
@VisibleForTesting for the same reason.
- Rename one of the estimatePredicateSelectivity overloads to estimateSelectivity, since
predicates aren't involved.
