We could add support for the cases like this:

contract C {
    receive("test") {}
    receive(msg: String) {
        let test1: String = "";
        test1 = "abc";
        test1 = "test";
        if (test1 == msg) {} // Bad
    }
}

It would be simpler to implement if we have an SSA IR (or any other IR that makes these assignments more explicit): #74
