[CSKY] Add CSKY buildbot to enable monitoring CSKY related commits

[zixuan-wu]

Summary

It runs check-all and test-suite to monitor the functional quality of CSKY target, when there is new related commit coming.
It runs llvm test-suite under QEMU to emulate the hardware target, and both in soft and hard-float mode.

Thanks, Zeson!

The patch looks good.
But could you remove the unrelated cosmetic changes, please?

Feel free to propose a separate pure cosmetic patch with this changes if you would like to.

I didn't change it by purpose. I think it's introduced by my local editor. I will figure out to remove it.
