  A TypeError should be thrown from GeneratorValidate (25.3.3.2) if the "this"

info: |
  1. Let g be the this value.
  2. Return GeneratorResume(g, value).

  25.3.3.3 GeneratorResume

  1. Let state be ? GeneratorValidate(generator).

  1. If Type(generator) is not Object, throw a TypeError exception.
