Philip Chimento 84f820258b harness: Remove hidden-constructors harness file
The objects it provides are also available in another harness file,
wellKnownIntrinsicObjects.js. There's no point in duplicating that in the
harness. Rewrite each test that used hidden-constructors.js to use
getWellKnownIntrinsicObject instead.

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.
