        HTML parser should provide script column position within HTML document to JavaScript engine
        https://bugs.webkit.org/show_bug.cgi?id=45271

        Adds TextPosition* classes -- a structure that stores line/column/generation
        level coordinates inside text document. Adds *BasedNumber classes -- typesafe int
        wrappers that emphasize whether int number is used as zero-based or
        one-based.

        Replaces line number with TextPosition struct so that script engine
        gets script starting line/column.
