code: static ConstantInterfaceMethodInfo make
          (ConstantPool cp,
           ConstantClassInfo parentClass,
           ConstantNameAndTypeInfo nameAndType) {
          
          ConstantInfo ci = 
              new ConstantInterfaceMethodInfo(parentClass, nameAndType);
          return (ConstantInterfaceMethodInfo)cp.addConstant(ci);
      }
docs: Will return either a new ConstantInterfaceMethodInfo object or
  one already in the constant pool.
  If it is a new ConstantInterfaceMethodInfo, it will be inserted
  into the pool.
