    // Caller method takes 5 parameters.  4 in register and 1 on the stack.  The important details here are that
    //  * Must take a value type as a parameter
    //  * The value type must be of size 1, 2, 4 or 8
    //  * That parameter must be passed on the stack.  Typically this is the 5th parameter and beyond for
    //    static methods, or 4th and beyond for instance methods.

        //  * Tail call optimizations must be enabled
        //  * The tail call optimization must fire (see above for an example of what might block it).
