Based on the Rust implementations: * https://github.com/rust-lang/rust/blob/2aabf3ce0569dd7c8c2d2a27944850056dcf2566/library/std/src/sys/sync/mutex/mod.rs#L3 * https://github.com/rust-lang/rust/blob/2aabf3ce0569dd7c8c2d2a27944850056dcf2566/library/std/src/sys/sync/mutex/futex.rs * https://github.com/rust-lang/rust/blob/2aabf3ce0569dd7c8c2d2a27944850056dcf2566/library/std/src/sys/sync/condvar/futex.rs This is a ~0.4% speedometer improvement on Windows (Linux and Android measurements in progress). This also adds a Linux implementation that will be enabled in a separate bug if worth it. Differential Revision: https://phabricator.services.mozilla.com/D300059
