Title: Fixes SI-6271 - Missing isEmpty override for views.

GenIterableView didn't override isEmpty for filter to look at *filtered* iterator, but was instead pulling
unfiltered iterator and causing issues. Chalk up another bizzare bug to lack of insight/visibility into
linearization and what havoc overriding new methods can spew on our library.

Review by @alex22, @paulp or anyone who loves inheritance (not the $$ kind).
