HTMLIsIndexElement should not expose HTMLInputElement properties

HTMLIsIndexElement should not expose HTMLInputElement properties

Reviewed by Adam Barth.

Source/WebCore:

document.createElement("isindex") should produce an HTMLUnknownElement
per the HTML5 spec.  The parser automagically translates <isindex> into
a whole dom tree roughly representing what <isindex> used to do 15 years ago. :)

This patch just removes our support for HTMLIsIndexElement.  The parser
support was already in.  Having support for HTMLIsIndexElement was causing
one of the IE TestCenter tests to fail.
