Erik Luo ce06603212 [debug] use flag to decide whether CallHandlerInfo has side effect 
Makes CallHandlerInfo its own instance type, with an additional
map to distinguish side-effect-free handlers. In a followup, we
can expose an API flag to set the map.

This CL does not support whitelisting calls to ObjectTemplates
that use SetCallAsFunctionHandler().

Heap Stats

Heap stats is a HTML-based tool for visualizing V8-internal object statistics. For example, the tool can be used to visualize how much heap memory is used for maintaining internal state versus actually allocated by the user.

The tool consumes log files produced by d8 (or Chromium) by passing --trace-gc-object-stats or a trace captured using Chrome's tracing infrastructure. Chrome trace files can either be processed as gzip or raw text files.

Hosting requires a web server, e.g.:

cd tools/heap-stats
python -m SimpleHTTPServer 8000
