New code should use nullptr instead of NULL.
This patch updates existing use of NULL to nullptr where applicable,
making the code base more consistent.

By adding a per test source file namespace, we can avoid a lot of

While we're at it, let's remove some "using" statements that also
cause trouble.

As part of J2V8 development (https://github.com/eclipsesource/J2V8),
we realized that we had a subtle bug in how Isolate scope was created
and it's lifetime managed, see:
https://github.com/eclipsesource/J2V8/issues/313.
Mentioned above bug was fixed, however, what we also noticed is that
V8 API has been constantly and slowly moving to such an API, in which
one has to pass Isolate explicitly to methods and/or constructors. We
found two more places that might have been overlooked. This contribution
adds passing of Isolate pointer explicitly to constructors of
String::Utf8Value and String::Value classes.

With TurboFan, there should no longer be any deopt loops (aside from
bugs). So, the "too many deopts" bailout is no longer needed, at least
in its current form.
This fixes an issue where deopt counts are leaked between native
contexts, resulting in optimization being disabled unnecessarily.

These are no longer necessary since we only have one optimizing compiler.
Also avoid changing --turbo-filter when --no-opt is set, and instead
explicitly check both the FLAG_opt and FLAG_turbo_filter in
GetOptimizedCode to check whether optimization is disabled.

Currently we count optimizations to decide to disable optimization, and
count deopts to detect this decision and allow re-enabling optimizations
after a while.
However, throwing out TurboFan OSR code and GC optimized code evictions
do not count as deopts, which means that the optimization count
increases without increasing the deopt count. This increased optimization
count disables further optimization -- which is bad, because these are
not "true" deopts -- and can stop the optimization from being re-enabled,
because the deopt count can't go high enough.
Instead, we now only ever look at deopts to disable/re-enable
optimization, and opt counts are only used for naming log files and in
tests.

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.

The patch introduces a dedicated dispatching class for JIT code events. It is
set as a helper on the isolate.
This allows classes across v8 to break their dependency on Logger and CpuProfiler.

Adds support for cpu profiler logging to the interpreter. Modifies the
the API to be passed AbstractCode objects instead of Code objects, and
adds extra functions to AbstractCode which is required by log.cc and
cpu-profiler.cc.
The main change in sampler.cc is to determine if a stack frame is an
interpreter stack frame, and if so, use the bytecode address as the pc
for that frame. This allows sampling of bytecode functions. This
requires adding support to SafeStackIterator to determine if a frame is
interpreted, which we do by checking the PC against pre-stored addresses
for the start and end of interpreter entry builtins.
Also removes CodeDeleteEvents which are dead code and haven't
been reported for some time.
Still to do is tracking source positions which will be done in a
followup CL.
