Auto merge of #130689 - RalfJung:rustc_nonnull_optimization_guaranteed, r=jieyouxu
fix rustc_nonnull_optimization_guaranteed docs As far as I can tell, even back when this was [added](https://github.com/rust-lang/rust/pull/60300) it never *enabled* any optimizations. It just indicates that the FFI compat lint should accept those types for NPO.
