[PATCH 0/8] MR9136: mshtml: Make Collection Enumerators part of the Cycle Collection graph.
From: Gabriel Ivăncescu gabrielopcode@gmail.com
Not just to avoid boilerplate for now, but needed when we have to convert them to be part of the Cycle Collection (it can form cyclic refs with the enumerator). That's why the collection pointer itself is part of the common impl, since it will have to be traversed.

Example of non-contrived cyclic ref:
document.body.foobar = function() {} var enumerator = new Enumerator(document.getElementsByTagName("body"));
body element (BODY) has a prop with a function (FUNC) which holds link to the enclosing scope (SCOPE). The scope holds link to "enumerator" (ENUM) which holds a link to the IEnumVARIANT of the element collection (ELEMCOL), which holds a link to body element. So: BODY->FUNC->SCOPE->ENUM->ELEMCOL->BODY.

This doesn't fix mentioned cycle on its own. We don't have JS/CC integration yet, so JS is not part of the CC graph anyway. Let's wait with the CC change until it makes sense.
As for sharing, it would perhaps be more interesting to have entire `IEnumVARIANT` interface shared instead of splitting it halfway. The caller could just pass a vtbl with `get_length(disp)` and `get_item(disp,index)` and remaining functions could be shared on top of that.

Ah right. I had some problems with the attribute collection though, since it uses relative next/skip. I added optional next/skip methods in the vtbl for that but I'm not sure if it's the best way, I can use them for all the others too if you prefer.
