Fixes string manipulation errors introduced in rust-lang#130446.
This was seen on Ferrocene, where we have a custom test target that does not have unwind support
Provide a more convinient way of developing rustc on NixOS This PR adds envrc files which, once symlinked as `.envrc` will activates a dev shell from `src/tools/nix-dev-shell/flake.nix` or `src/tools/nix-dev-shell/shell.nix`. This is based on - [Current rustc dev guide recommendation for NixOS](https://rustc-dev-guide.rust-lang.org/building/suggested.html?highlight=nix#using-nix-shell) - https://github.com/oxalica/rust-overlay?tab=readme-ov-file#use-in-devshell-for-nix-develop - [Nora's `x` nix package](https://github.com/Noratrieb/nixos/tree/26ea68e1a0aadaab313c1b5a8c1033a9770bd138/custom-pkgs/x) - rust-lang/rustup#2891 - [Direnv: use flake/nix according to availability](https://discourse.nixos.org/t/direnv-use-flake-nix-according-to-availability/29825) This is something that I plan to use personally, but I thought it might be worth upstreaming :) r?

Add `must_use` to `CommandExt::exec` [CommandExt::exec](https://fburl.com/0qhpo7nu) returns a `std::io::Error` in the case exec fails, but its not currently marked as `must_use` making it easy to accidentally ignore it. This PR adds the `must_use` attributed here as i think it fits the definition in the guide of [When to add #[must_use]](https://std-dev-guide.rust-lang.org/policy/must-use.html#when-to-add-must_use)
…ribute-unwind, r=Noratrieb Do not run test where it cannot run This was seen on Ferrocene, where we have a custom test target that does not have unwind support
Add mailmap entry for kobzol Hopefully I got this right.
