vogelheim 6f9d60cc6f Implement AggregatableHistogramTimer and use it to measure how much time 
of running a script is really spent in compilation. That is, sum up the
total time spent compiling (parsing + compile proper) within a run call
as seen through the API.

@jochen: So many questions:
- Is it ok to re-use V8.CompileLazy?
  This measures something a little different.
- clang-format does funny things to the huge macro definitions.
  I accepted clang-format changes for all code, but reverted for
  the #define orgies in counters.h. ok?
- Am I measuring the right thing. That is, are Aggregat[ing|ed]TimerScope
  in the right place?

I'll fiddle a bit more with this to see if it does the right thing. Would
be happy if you could still review now-ish.

Getting the Code

Checkout depot tools, and run

fetch v8

This will checkout V8 into the directory v8 and fetch all of its dependencies. To stay up to date, run

git pull origin gclient sync

For fetching all branches, add the following into your remote configuration in .git/config:

    fetch = +refs/branch-heads/*:refs/remotes/branch-heads/*
    fetch = +refs/tags/*:refs/tags/*
