        Batch compile the set of static trampolines at the point Machine is constructed, using a single allocation.
        Refactor out m_callFrame from CTI, since this is only needed to access the global data (instead store a
        pointer to the global data directly, since this is available at the point the Machine is constructed).
        Add a method to align the code buffer, to allow JIT generation for multiple trampolines in one block.
