                                           boolean allowCompactCompletionFrame)
        Creates a new stack map frame handler that expects the original frames to be preserved.
        Parameters:
        instrumentedType - The instrumented type.
        instrumentedMethod - The instrumented method.
        initialTypes - A list of virtual method arguments that are explicitly added before any code execution.
        preMethodTypes - A list of virtual method arguments that are available before the instrumented method is executed.
        postMethodTypes - A list of virtual method arguments that are available after the instrumented method has completed.
        expandFrames - true if the meta data handler is expected to expand its frames.
        allowCompactCompletionFrame - true if a completion frame for the method bust be a full frame to reflect an initialization change.

                                   java.lang.Object[] stack)
        Translates a frame.
        Parameters:
        methodVisitor - The method visitor to write the frame to.
        type - The frame's type.
