These may change across Rust versions, so we just use all the libraries in rlibs, which should be kept up to date by mir-json-translate-libs
We never used it for anything, and it is now removed on the mir-json side

Yeah, it's in test/conc_eval/cell/swap.rs. There are also a few crux-mir-comp tests that use it.
