Allow form inputs to be potential cluster roots.

We check for form inputs in blockSuppressesAutosizing, but the block
must be a potential cluster root to reach this check.

Enable Oilpan for ImageBitmapFactories::ImageBitmapLoader by default.

We can't enable Oilpan for ImageBitmapFactories, another class in
modules/imagebitmap/, because it's a Supplement of DOMWindow or
WorkerGlobalScope.

Drop traverseNextElement() method from HTMLCollection class

Drop traverseNextElement() method from HTMLCollection class to avoid code
duplication with traverseForwardToOffset(). This method was only used
by supportedPropertyNames() and updateIdNameCache(). Now these methods
uses the standard traversal API (HTMLCollection::length() / item(index)),
and thus the standard code path for HTMLCollection traversal.

I did not see any regression with this change on Dromaeo:
