instance_class_name takes up space unnecessarily, and %_ClassOf and
class_name implement [[Class]] which isn't part of ES2015+ anymore.

Also, make %GeneratorGetSourcePosition fail if called on a suspended Ignition generator
(rather than return nonsense). This functionality is currently not implemented.

When setting a generator function's "prototype" property to a non-object, the
prototype of new generator instances should be %GeneratorPrototype%, not
%ObjectPrototype%.

ES2015 Object.prototype.toString semantics were enabled in version 4.9,
which has been in stable Chrome for nearly two weeks at this point.

The removed assertion consistently passes not because the invoked
`close` method internally throws a `TypeError` but because the `close`
method does not exist. The ES6 specification does not define a `close`
method on the GeneratorPrototype, so this test is a tautology.

Updates Object.prototype.toString() to use algorithm described in harmony drafts.
Currently, the behaviour is essentially the same as ES262's version, however this changes when internal structures
such as Promise make use of symbolToStringTag (as they are supposed to, see v8:3241), and changes further once
Symbol.toStringTag is exposed publicly.
