Shouldn't we keep having a test for "Iterable" extended attribute? We still
support it.

[Jens Widell, 2015/01/09 07:15:04]

Done.

I've reverted the change to this file, and instead added iterable<any> to
TestInterface3.

     SetWrapperReferenceTo(TestInterface referencedName),
     TypeChecking=(Interface,Unrestricted),
     Exposed=(Worker,Window),
 ] interface TestInterface : TestInterfaceEmpty {
     // members needed to test [ImplementedAs], as this affect attribute
     // configuration and method configuration, and [TypeChecking]
     // constants also needed for [DoNotCheckConstants]
     const unsigned long UNSIGNED_LONG = 0;
