Rather than introduce an AtomicString -> HTMLIdentifier conversion, I would have
just overloaded this function.

Which conversion do you mean here? The only place I'm introducing a conversion
like that (I think?) is in the PageSerializer.cpp, and that doesn't call into
HTMLTokenizer, it calls into HTMLMetaCharsetParser.
