never check for degenerates in path::iter

This does not appear to be used externally, and only internally in 3
sites in GPU, which we can handle explicitly.

For now you can still pass bools to Iter::next() but they are ignored.
After this lands, I will update the callers to remove those.

FWIW: none of our other tests or gms seem to notice this change...
