Original issue's description:
> Refactor CpuProfiler.
>
> Currently CpuProfiler is a subclass of CodeEventListener, it listens code events
> from Logger, constructs and stores CodeEventsContainer. This patch is part of
> the effort to split the logic of CodeEventListener as ProfilerListener out of
> the profiling functionality logic in CpuProfiler. A ProfilerListener will listen
> to code events, construct code event to CodeEventsContainer and pass it to code
> event handler.
>
> The reason we refactor CpuProfiler is that eventually we want to move
> CpuProfiler as part of sampler library and code event listener should stay
> inside V8.
>
> Main changes:
> 1. Refactored CpuProfiler into two parts, the CpuProfiler with profling
> functionality and the ProfilerListener listening to code events from Logger.
> 2. Created CodeEventObserver and made CpuProfiler inherit from it.
> ProfilerListener will have a list of observers and call CodeEventHandler once a
> code event is created.
> 3. Moved code entry list from CodeEntry to ProfilerListener.
>
> Minor changes:
> 1. Moved static code entry as part of CodeEntry.
> 2. Added ProfilerListener to Logger.

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.
