code: private boolean prescreen(Method obj) {
          BitSet bytecodeSet = getClassContext().getBytecodeSet(obj);
          return (bytecodeSet != null) && ((bytecodeSet.get(Const.LDC) || (bytecodeSet.get(Const.LDC_W))));
      }
docs: looks for methods that contain a LDC opcode
  
  @param obj
  the context object of the current method
  @return if the class uses LDC instructions
