Cache and reuse the HTMLAllCollection returned by document.all.
<http://webkit.org/b/74768>
Reviewed by Antti Koivisto.
Source/WebCore:
Let Document cache the document.all collection, just like we do for
the other collections (.links, .images, etc.)
This is primarily a memory optimization, as repeated calls to
document.all will no longer cause collection objects to stack up.
