Have `pyperformance run` run `pyperf system tune`

I was surprised to learn today that pyperformance run does not call pyperf system tune -- I guess I had assumed that this was included in pyperformance's responsibilities. It looks like support was added to run it for pyperformance compile but not for pyperformance run so I'm not sure what is intended.

I'd like to propose that pyperformance run and pyperformance compile have the same behavior with respect to tuning the system, with my personal preference being that they should both tune the system. What do you all think?

比较 pyperformance compile 与 pyperformance run 的现有行为，重点关注每个命令调用 pyperf system tune 的位置。根据 issue 讨论确认预期的共享调优行为，然后使两个命令保持一致，并验证两条命令路径。
