It's running.  There are a couple of things to note. I'm only able to run perf testing on a downstream compiler with quite limited number of benchmarks.
Thus evaluation of performance impact will be based on that and in theory might differ for llvm-project.
And there will be no performance numbers - just can say whether looses/gains are expected.
