      Add aggregated memory histograms. · d77839fd
      ulan authored
      This introduces V8.MemoryHeapCommitted and V8.MemoryHeapUsed histograms.
      
      In contrast to the existing memory histograms, the new histograms are uniform in time, i.e. their samples happen at regular time intervals. The --histogram-interval specifies the length of the interval.
      
      We implement this by linearly interpolating memory stats between GC and idle notification events.

      Implement AggregatableHistogramTimer and use it to measure how much time · 6f9d60cc
      vogelheim authored
      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.
