Original issue's description:
> [Reland][Tracing] Embed V8 runtime call stats into tracing.
>
> Currently we have V8 RuntimeCallStats that is independently from tracing when
> running d8 with flag --runtime_call_stats. This patch embeds V8 runtime call
> stats into tracing, by having a global table of runtime call counters each
> isolate, resetting the table each time we enter a top level trace event, and
> dumping the table for each top level trace event. This will make trace file more
> compat, as well as enable runtime call stats in tracing system.
>
> This patch adds ~5% overhead to V8 when the category is enabled, we measure the
> overhead by running a script when category is enabled.

No L-G-T-M from a valid reviewer yet. 
CQ run can only be started by full committers or once the patch has
received an L-G-T-M from a full committer.
Even if an L-G-T-M may have been provided, it was from a non-committer,
_not_ a full super star committer.
Committers are members of the group "project-v8-committers".
Note that this has nothing to do with OWNERS files.
