commit 295c9cc643a2a5e410207fd1f4634ad9c8c83405
Author: Alexei Filippov <alph@chromium.org>
Date: Wed Nov 08 19:48:40 2017

[cpu-profiler] Add static CollectSample method to the CpuProfiler API.

The method forces all running profilers attached to the provided isolate
to collect a sample with the current stack.

It is going to be used to synchronize trace events generated by embedder with the samples
collected by the profiler.

Also it will finally allow us to break dependency of isolate on CPU profiler.
