    Behavior when `hint` is "string" and first try is not callable
info: |
    1. Let O be the this value.
    2. If Type(O) is not Object, throw a TypeError exception.
    3. If hint is the String value "string" or the String value "default", then
       a. Let tryFirst be "string".
    4. Else if hint is the String value "number", then
       a. Let tryFirst be "number".
    5. Else, throw a TypeError exception.
    6. Return OrdinaryToPrimitive(O, tryFirst).
