(Alternatively we could just delete these, but they do seem plausibly useful to somebody, and with the new implementation they’re not so bad.) |

Rollup merge of rust-lang#132590 - Zalathar:z-timings-stats, r=jieyouxu Simplify FFI calls for `-Ztime-llvm-passes` and `-Zprint-codegen-stats` The existing code for these unstable LLVM-infodump flags was jumping through hoops to pass an allocated C string across the FFI boundary, when it's much simpler to just write to a `&RustString` instead.
