-This patch is taken from upstream and helps the test pass on all architectures.
-
-The adjustment to absl/numeric/internal/bits.h was removed since the file
-didn't appear in the git checkout.

-Weaken Duration.ToDoubleSecondsCheckEdgeCases and
-Duration.ToDoubleSecondsCheckRandom to make them less sensitive to fused
-multiply/add contraction.
