        Fixed version of: "Optimized o[s] where o is a cell and s is a string"
        https://bugs.webkit.org/show_bug.cgi?id=38815

        Fixed the previous patch for this from Geoff Garen.

        The two problems were a missing exception check and a PropertySlot
        initialized improperly, leading to crashes and failures in the case
        of getters accessed with bracket syntax.

    Previous patch:

        Optimized o[s] where o is a cell and s is a string, removing some old
        code that wasn't really tuned for the JIT.

        SunSpider says 0.8% faster.
