- allow flags on terminal ops.
- propagate terminal ops through the distinct pipeline stages.
(No action performed yet, but the plan is to back propagate NOT_ORDERED.)
- re-introduce optimization if pipeline depth is zero and supplier of
spliterator is backed by a Node.
- ensure {Int}Stream.parallel() is lazy and does not unpack the spliterator
from the source supplier or from the wrapping spliterator until
evaluation occurs.
