Introduce -Zprofile-closures to evaluate the impact of 2229
This creates a CSV with name "closure_profile_XXXXX.csv", where the variable part is the process id of the compiler. To profile a cargo project you can run one of the following depending on if you're compiling a library or a binary: ``` cargo +stage1 rustc --lib -- -Zprofile-closures cargo +stage1 rustc --bin -- -Zprofile-closures ```
