Bump stdarch

[daxpedda]

This bumps stdarch to rust-lang/stdarch@684de0d to get in rust-lang/stdarch#1677 (tracked in #133908).

From the commit history I deduced that there shouldn't be any changes to Rust necessary.

From past PRs I'm assuming that bumping stdarch like this is fine, but please let me know if this is somehow inappropriate or requires something more to be done!
