        Fix for https://bugs.webkit.org/show_bug.cgi?id=20515 Crash upon 
        parsing CSS: unicode-range: searchfield-cancel-buttonpt=-webkit-

        This patch makes CSSParserValue::createCSSValue handle unknown 
        identifiers.

        * css/CSSParserValues.cpp:
        (WebCore::CSSParserValue::createCSSValue): If we have an identifier 
        with no id (an unknown identifier) create a CSSPrimitiveValue of 
        type CSS_PARSER_IDENTIFIER
        * css/CSSPrimitiveValue.cpp:
        (WebCore::CSSPrimitiveValue::cssText):
        (WebCore::CSSPrimitiveValue::parserValue):
        * css/CSSPrimitiveValue.h:
        (WebCore::CSSPrimitiveValue::):
