Re-land https://codereview.chromium.org/23602005: Use nobarrier atomics for lossy counters in base::HistogramSamples and base::SampleVector
This should not affect the performance, but will make it explicit that the counter values are expected to be read and written atomically.
This will also suppress the ThreadSanitizer v2 reports on these counters.
