Remove usage of deprecated --prof-lazy V8 command line flag

This flag was introduced to implement log-based CPU profiler in DevTools in r17866. The profiler has been rewritten since then. The old API is deprecated in V8 (https://code.google.com/p/v8/source/detail?r=15828) and will be removed soon.
