Reviewed by Ryosuke Niwa.

Revive support in the HTML parser for <hr>-in-<select>, thereby making an existing UI feature much more accessible to web developers.

This reflects a recent change in the HTML Standard: https://github.com/whatwg/html/pull/9124.

* LayoutTests/html5lib/resources/webkit02.dat:

These are being upstreamed via https://github.com/html5lib/html5lib-tests/pull/167 and will then be incorporated into web-platform-tests.

* Source/WebCore/html/parser/HTMLTreeBuilder.cpp:
(WebCore::HTMLTreeBuilder::processStartTag):
