Add basic plumbing for TopDown in perf stat
TopDown is intended to replace the frontend cycles idle/
backend cycles idle metrics in standard perf stat output.
These metrics are not reliable in many workload

Add basic plumbing for TopDown in perf stat
TopDown is intended to replace the frontend cycles idle/
backend cycles idle metrics in standard perf stat output.
These metrics are not reliable in many workloads,
due to out of order effects.
