stage2: implement argument passing and returning in LLVM backend

Furthermore add the Not instruction.

The following now works:
```
export fn _start() noreturn {
    var x: bool = true;
    var other: bool = foo(x);
    exit();
}

fn foo(cond: bool) bool {
    return !cond;
}

fn exit() noreturn {
    unreachable;
}
```
