692d3df279e7592d01c1008cb85f2a010c3d17da by Abseil Team <absl-team@google.com>:

Use EXPECT_DEATH_IF_SUPPORTED instead of raw EXPECT_DEATH.

ebc40936b677b79cad9f87f944794c35946f9dbd by Gennadiy Rozental <rogeeff@google.com>:

Eliminate SetCallback from absl::Flag<T> public interface.

We also make SetCallback on FlagRegistrar to return rvalue, so that we can add more tail calls after it.
