When adding samples to the counter in the test body, most of them get added at the same time (rtc::TimeMicros()). This means that the comparator [2] is not able to sort them explicitly (for the comparator they are equal). PerfTest.TestGetPerfResultsHistogramsWithStatsCounter was relying on std::sort implementation being stable, but it is not. If stability is needed, std::stable_sort should be used so this CL switches ::webrtc::test:GetSortedSamples() to std::stable_sort.
