Describe

支持保存加载Program.
示例：

def test_save_load_program(self):
    paddle.enable_static()
    
    layer = LinearNet()
    data = paddle.static.data(
        name='x_static_save', shape=(None, IMAGE_SIZE), dtype='float32')
    y_static = layer(data)
    main_program = paddle.static.default_main_program()
    startup_program = paddle.static.default_startup_program()
    origin_main = main_program.desc.serialize_to_string()
    origin_startup = startup_program.desc.serialize_to_string()
    path1 = "test_paddle_save_load_program/main_program.pdmodel"
    path2 = "test_paddle_save_load_program/startup_program.pdmodel"
    paddle.save(main_program, path1)
    paddle.save(startup_program, path2)

    load_main = paddle.load(path1).desc.serialize_to_string()
    load_startup = paddle.load(path2).desc.serialize_to_string()
    print(origin_main == load_main)
    print(origin_startup == load_startup)
