Update dependencies to use new_debug_unrechable

Because reem/rust-debug-unreachable#6 makes `debug_unreachable` enable debug checks even in release builds since Rust 1.0.

This adds a duplicate dependency on `unreachable` until I have time to fork `ordered-float`, but it's a tiny dependency so we don't care.
