(WebCore::Style::createTextRenderersForSiblingsAfterAttachIfNeeded):
        
    Factor to take reference and do the inital tests itself.

(WebCore::Style::createTextRendererIfNeeded):
(WebCore::Style::updateTextRendererAfterContentChange):
(WebCore::Style::attachChildren):
        
    Also tightened the condition where previously attached children may be encountered.
