        Add site-specific hack for zipcar.com with old versions of requirejs.
        https://bugs.webkit.org/show_bug.cgi?id=61321

        Old versions of requirejs (< 0.15.0) try to load scripts in parallel but execute them in
        order. This used to work in webkit by setting a bogus script type (script/cache), then
        changing the type to a valid one when they wanted to execute it. This hack translates the
        behavior into the new API (by disabling forceAsync).

        * html/HTMLScriptElement.cpp:
        (WebCore::needsOldRequirejsQuirk): Added.
        (WebCore::HTMLScriptElement::insertedIntoDocument):
        If hack is needed, set a proper script type so script loads.
        If script isn't async, disable forceAsync so script executes in order.
