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?

So sánh hành vi hiện tại của pyperformance compile với pyperformance run, tập trung vào nơi mỗi lệnh gọi pyperf system tune. Xác nhận hành vi tinh chỉnh dùng chung dự kiến từ phần thảo luận của issue, sau đó làm cho các lệnh nhất quán với nhau và kiểm tra cả hai đường dẫn lệnh.
