Chrome: Enable ChromeOS-Wide-Profiling
We want to gather perf data collected by running "perf record -a" from opt-in
ChromeOS users. This CL enables that.
We use debugd in ChromeOS to run quipper, a program that runs "perf record -a"
and returns that data in a protobuf. We do this every 12 hours for 2 seconds.
The overhead is minimal (5% slowdown for 2 seconds on "lumpy" machines).
BUG=157508
TEST=Manual:
Change the perf record interval from 12 hours to 1 minute and set a
breakpoint on ParseProtoIfValid(). It gets hit and the protobuf is parsed
properly.
