🦀 I've improved the implementation behind all the string formatting macros in Rust: println, panic, format, write, log::info, etc. (Everything using format_args!().) They will compile a bit faster, use a bit less memory while compiling, result in smaller binaries, and produce more efficient code! 🎉

The before version has 11 instructions and stores 56 bytes on the stack. The after version has 3 instructions and stores no data on the stack.
