        Use WebKit macro to detect 64bit in RenderLayerBacking.h
        https://bugs.webkit.org/show_bug.cgi?id=224707

        Reviewed by NOBODY (OOPS!).

        There's no definition of __WORDSIZE in some environment. Also there's WebKit macro for that.

        > warning: '__WORDSIZE' is not defined, evaluates to 0 [-Wundef]
        > #if __WORDSIZE == 64 && PLATFORM(COCOA)
        >     ^

        No test because it's compiler behavior.
