Description

Rust 1.91 is out and stabilized the first round of these: https://blog.rust-lang.org/2025/10/30/Rust-1.91.0/

Note they're not yet usable in const fn, so maybe not quite up to our needs yet.

Edit: per the stabilization PR constifying them is blocked on const traits, so that may be awhile unless the underlying implementation changes

Research direction

No file or test is named. Start by locating the existing bigint carry, borrow, multiply, and multiply-add helpers, then compare their use with Rust 1.91's stabilized core methods. Done means the applicable helpers use those methods without losing required const-fn support; the issue notes that const use is currently blocked.
