  The GeneratorFunction constructor implements [[Construct]]
info: |
  IsConstructor ( argument )

  The abstract operation IsConstructor takes argument argument (an ECMAScript language value).
  It determines if argument is a function object with a [[Construct]] internal method.
  It performs the following steps when called:

  If Type(argument) is not Object, return false.
  If argument has a [[Construct]] internal method, return true.
  Return false.
