    perf session: Pass evsel in event_ops->sample() · 9e69c210

    Resolving the sample->id to an evsel since the most advanced tools,
    report and annotate, and the others will too when they evolve to
    properly support multi-event perf.data files.
    
    Good also because it does an extra validation, checking that the ID is
    valid when present. When that is not the case, the overhead is just a
    branch + function call (perf_evlist__id2evsel).
