86078dfd7b Add a percentage to each metric in the V8 timeline plot 
With the percentage, we can easily figure out how much execution time is spent in what metric.

1074e1f558 Fix the xrange calculation of the V8 timeline plot 
Currently an xrange is calculated by V8.Execution. This would be fine for JavaScript benchmarks in which everything happens inside of V8.Execution. On the other hand, in Chrome profiling, events can happen outside of V8.Execution. To visualize such outside events, we need to calculate an xrange so that the xrange covers all events.

f6659cfcd7 Recently I tried to debug CPU profiling on Chrome. 
I've found that profiling is not working in Debug version.
The actual problem is that sandbox/playgroung configuration is wrong and tgkill syscalls are disallowed.

This patch will make such cases more clear.

1ac3949a93 Removed deprecated functions from v8's external API. 
Removed the following deprecated functions:

   * Object::GetPointerFromInternalField
   * Object::SetPointerInInternalField
   * External::Wrap
   * External::Unwrap
   * Context::GetData
   * Context::SetData

They have been deprecated in the 3.15 branch and are not used by Chrome anymore.
Furthermore, judging from bug reports and email threads, embedders like node.js
and others are already using 3.15, too. All removed API entries can be emulated
by a one-liner, so adapting should not be hard for anybody.

We want to introduce more deprecations soon, but to keep things simple and avoid
having old and not-so-old deprecations in v8.h, the 3.15 deprecations are now
removed.

In general, the strategy of keeping deprecated things for one stable release and
then removing them seems to be a good compromise between a maintenance nightmare
and annoying external embedders. :-)
