Use std::hint::black_box consistently. 

This also removes the `#![feature(bench_black_box)]`. This was
stabilized in Rust 1.66 and anyone building benchmarks will be
on that or later (as they previously would have been on nightly).

This also allows building `cargo build --all-targets` on stable
Rust as it no longer dies when hitting the feature addition in
the benchmarks.
