This reverts commit 9def3b45ef06de9e068e8f4d1644e9d508baa913.
Reason for revert: webrtc_perf_tests fails on Mac-10.12.
Original change's description:
> Second reland of "Optimize execution time of RTPSender::UpdateDelayStatistics"
>
> The reland has a lot of additional DCHECKS for easier debugging,
> so in debug builds it will actually be a ~2x slowdown compared to the old code.
> The excessive DCHECKS should be removed in a followup CL.
>
> Bug: webrtc:9439
