        Canvas/JSC: Auto-generate overloads for setFillColor()
        https://bugs.webkit.org/show_bug.cgi?id=61635

        Move CanvasRenderingContext2D.setStrokeColor() to auto-generated JSC bindings.

        There is a subtle difference to the previous behavior: invalid numbers of
        arguments now raise TypeError instead of SyntaxError. This is in accordance
        with Web IDL, but doesn't matter much anyway since this method is WebKit-only.

        Test: fast/canvas/canvas-overloads-setFillColor.html
