1. `Parallel Compiler`：
    - 合并`FLAGS_cinn_parallel_compile_size`和`FLAGS_cinn_parallel_compile_thread`，通过`FLAGS_cinn_parallel_compile_thread`即可指定编译时使用的线程数，所有的`fusion_groups`将会平均分配到可用的线程上
    - 增强编译完成后返回的信息，除`instruction`外，将`lowered_function`、`source_code`、`source_ptx`返回，供上层进一步使用
2. Debug信息：
    - 新增`FLAGS_ cinn_dump_group_lowered_func`、`FLAGS_cinn_dump_group_source_code`、`FLAGS_ cinn_dump_group_ptx`、`FLAGS_ cinn_dump_group_instruction`，可分别按`fusion_groups`储存编译的每个阶段中的中间代码
    - 重新整理`graph_visualization`，所有的可视化图、单测代码均能正确分组储存
3. Bug修复：
    - 修复`MakeDirectory`不能正确创建文件夹的问题
4. 其他：
    - 清除了一些无用代码
