[zorg] Add buildbot for Synopsys ARC

[Lily_He]

Summary

Create AWS worker for LLVM Experimental Target : ARC

[gkistanova]

Looks good with a nitpick.

Unless I'm missing something, you do not really need to specify llvm_srcdir, obj_dir, and clean. The defaults should work well for your case. They are specified for the nearby builders, but that's for the backward compatibility for builders which are around for a long time.

Please feel free to commit with these changes.

If you don't have a strong reason to define the name of the source code root, you could just skip this param and use the default name.

1878

If you don't have a strong reason to define the name of the build directory, you could just skip this param and use the default name.

1879

If you do not want to force always clean builds, you can just skip this param.
