Motivation: Protocols like Sequence have "private" hooks that can be implemented to provide fast-paths for some operations. We missed a few on BBV, and I'd like to add them. This is one use-case where they can help. Modifications: - Add an allocation-counter benchmark and a runtime benchmark for copying BBV to Array. Result: We have some benchmarks.
