      [Tracing] Fix inaccurate timer calculation in runtime statistics. · 92d9a56a
      lpy authored
      Previously we reset runtime counters and dump them when we enter, exit top level
      trace events respectively. However, there is gap between two top level trace
      events and runtime counters may be activated, resetting the counters makes the
      accumulated time inaccurate, and we may end up with negative time due to the
      nature of how we accumulate time.
      
      This patch fixes this problem by only resetting counters when there's no
      counters active, and before dump counters, we traverse current active counters
      to calculate their time, and then restart their timer.

      [RuntimeCallStats] Move tracing runtime instrumentation closer to the original version. · e5ba156d
      fmeawad authored
      After we landed the tracing runtime call stats, which gave
      us a lot of V8 insight in tracing, we noticed that there is
      some arising issues and discrepancies.
      
      Issues include:
      Missing trace events, that happened due to
      transforming those trace events into runtime calls
      
      Discrepancies include:
      Missing categories in Runtime call stats like GC,
      because we are not handling the Scoped runtime calls
      properly in the tracing version.
      
      To reduce/eliminate those issue, we are taking a small
      step back. We are unifying the RuntimeStats code and
      using the original one. That would allow us to use all
      the original probes but emit trace events from them.
      We are also putting back the trace-events in their place.
      
      The output from both system should be intact (Except of
      the addition of the missing trace-events).
      
      Also as a byproduct, we are reducing the number of context
      scopes by half since we are using the same scope as
      runtime call stats.
      
      As a follow up to this CL, we will address the non-scoped
      Runtime Call Stats (mainly in GC).
