Details

Similar to bug 1071880, but send the data back using telemetry.
Maybe add a PROFILER_LABEL call so BHR will report the frame?
Actually, the data is already uploaded with PERF_MONITORING_SLOW_ADDON_CPOW_US. We need post-processing to sort worst offenders.
CPOW frames show up well in the latest BHR stacks (an example: https://gist.github.com/chutten/1c1df7314f480603a6df ) An analysis using PERF_MONITORING_SLOW_ADDON_CPOW_US should prove useful as well, though it will show heavy CPOW users even if the CPOW doesn't cause jank.
