Fix clippy::needless_late_init
Browse files Browse the repository at this point in the history
Used `cargo clippy -- -A clippy::all -W clippy::needless_late_init` to find all such cases, and manually fix them

Additionally simplified logic in backward_references/hq.rs, and converted while into for loop there
