bmeurer@chromium.org e2b4525397 Reland "Add Chromium-style TimeDelta, Time and TimeTicks classes, and a new ElapsedTimer class." ... These classes are meant to replace OS::Ticks() and OS::TimeCurrentMillis(), which are broken in several ways. The ElapsedTimer class implements a stopwatch using TimeTicks::HighResNow() for high resolution, monotonic timing. Also fix the CpuProfile::GetStartTime() and CpuProfile::GetEndTime() methods to actually return the time relative to the unix epoch as stated in the documentation (previously that was relative to some arbitrary point in time, i.e. boot time).
