opbenchmark配置全吗？ |
op-benchmark 配置是全的，6号、7号和8号是fp16，脚本不支持。此现象非此PR引入，原本就存在，需要处理，但不在此PR内。 |

Sorry to inform you that 2badce0's CIs have passed for more than 7 days. To prevent PR conflicts, you need to re-run all CIs manually. |

功能
该PR使用新的接口优化了elementwise_max的反向计算
效果
整体上讲，优化后性能均优于竞品；但就前4个配置，优化后较优化前性能差；其他配置优化后性能显著优于优化前：
整体上，优化3（适配多输出代码优化后)较优化1（reduce接口优化)、优化2（三元functor优化）均有显著提升；但当前前两个配置差于dev 10%左右；
