-From: Benjamin Barenblat <bbaren@google.com>
-Subject: Make tests tolerant of FMA contraction
-Forwarded: yes
-Applied-Upstream: https://github.com/abseil/abseil-cpp/commit/b0735979d778a768caee207f01f327535cbd2140
-
-Weaken Duration.ToDoubleSecondsCheckEdgeCases and
-Duration.ToDoubleSecondsCheckRandom to make them less sensitive to fused
-multiply/add contraction.

-The author works at Google. Upstream applied this patch as Piper
-revision 360297653 and exported it to GitHub; the the Applied-Upstream URL
