It seems that we are currently building Rust code in Firefox with opt-level=2 for shipping binaries. Should we consider bringing that up to level 3?
There are certain optimizations which level 2 doesn't do while level 3 does. I just discovered one case, see rust-lang/rust#46542, which I hope Rust can optimize while it doesn't do so until level 3.

It's possible to the optimization level per crate: https://doc.rust-lang.org/nightly/cargo/reference/profiles.html#overrides
So I don't think we need this bug anymore.
