code: def put_conditional(self, cond, valiftrue, valiffalse, reg):
          
  
          val = self.irsb_c.ite(cond.rdt , valiftrue.rdt, valiffalse.rdt)

docs: Like put, except it checks a condition
          to decide what to put in the destination register.
  
          :param cond: The VexValue representing the logical expression for the condition
              (if your expression only has constants, don't use this method!)
          :param valiftrue: the VexValue to put in reg if cond evals as true
          :param validfalse: the VexValue to put in reg if cond evals as false
          :param reg: The integer register number to store into, or register name	
          :return: None
