Tiny compiler in 500 lines of Rust

Write a tiny compiler in 500 lines of rust to run hello world in cargo init template.

fn main() {
    println!("Hello, world!");
}

It's very simple but still includes a hand-coded lexer, parser (LL1) and LLVM IR codegen. I didn't implement the resolver part because the example code is simple enough that I assume it will always be right.
