(WebCore::CSSSelectorParser::consumeForgivingComplexSelectorList): Use it for complex selector lists. (WebCore::CSSSelectorParser::consumeForgivingRelativeSelectorList): And the new relative selector lists. (WebCore::CSSSelectorParser::consumeRelativeSelector): Parse relative selectors like "> foo".
