  perftests: Record trace events to JSON file.
  
  This allows us to view the timeline of events in the trace event
  browser. We can extend this to do GPU timestamp queries and analyze
  when work is actually in flight.
  
  The trace is enabled in standalone ANGLE only using the flag
  --enable-trace with angle_perftests. You can also optionally specify
  the trace output file with --trace-file <blah>. The default file is
  ANGLETrace.json.
