Ideally, we need to avoid counting these events. In this commit, at the time when a retire_latency evsel is read, set the re= tire latency value processed from the sampled data to count value. This sampled retire latency value will be used for metric calculation and final event co= unt print out. No special metric calculation and event print out code required = for retire_latency events.
