        The current implementation of generate_fixed_frame unnecessarily reloads fields from memory. Most prominent is the reload of ConstMethod* (5 times).
        In addition, unneeded monitor space is allocated in the top frame. Space for monitors gets added on demand (lock_method uses add_monitor_to_stack).
        Also, implementation can get simplified by using MacroAssembler::Clear_Array.
