      Behavior when `hint` is "default" and neither first nor second try are 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).
