    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.
