Compiler hangs on recursive functions when targeting Metal

[dbartussek]

Attempting to compile the following code targeting Metal results in the compiler hanging:

[shader("compute")]
func m() {
    r();
}

func r() {
    r();
}

I stumbled on this while messing around in the playground: https://shader-slang.com/slang-playground/?target=METAL&code=eJyLLs5ITEkt0lBKzs8tKC1JVdKM5UorzUtWyNXQVKjmUgCCIg1Na65aLohwEZowAHEsEU0
