I also replaced {{hasOnlyEqualityRestrictions()}} with a simple for-loop while
I was at it.

>
> While profiling local in-memory reads for CASSANDRA-10993, I noticed that
> {{RestrictionSet.hasIN()}} was responsible for about 1% of the time. It
> looks like it's mostly slow because it creates a new LinkedHashSet (which is
> expensive to init) and uses streams. This can be replaced with a simple for
> loop.
