Steps to reproduce the problem:
1. Use V8-profiler on latest chrome version.
2. Load the profile generated to Performance tab in devtools.
3. It doesn't display anything.

What is the expected behavior?
The v8-profiler is using some apis to get the performance data in json file in some format but I guess the format has changed (got this by recording and saving performance data).

What went wrong?
Current chrome can't read the json file generated by v8-profiler.

Did this work before? Yes 58

Does this work in other browsers? N/A

Chrome version: 63.0.3239.132  Channel: n/a
OS Version: 10.0
Flash Version: 

Please let me know asap if there are apis supported by chrome to record cpu profile (stack trace etc.) and save them locally.
