        HTML5 TreeBuilder builds wrong DOM for <a><svg><tr><input></a>
        https://bugs.webkit.org/show_bug.cgi?id=44390

        The HTML5 spec has changed since Adam and I original wrote
        the HTMLTreeBuilder.  Most important for this change was resolution of:
        http://www.w3.org/Bugs/Public/show_bug.cgi?id=9580

        I also removed our "phrasing" tag support since that was also removed
        from the spec as part of other bug fixes.

        This is tested by tonyg's <a><svg><tr><input></a> test in adoption01.dat.
