de82143f509d8fd6e70efc9eaed35582054a7443 by Abseil Team <absl-team@google.com>:

Mark optional::reset() with the ABSL_ATTRIBUTE_REINITIALIZES attribute.

This prevents false positives in the clang-tidy check bugprone-use-after-move; it allows reset() to be called on a moved-from optional without any warnings, and the optional will thereafter be regarded as initialized again.

Mark //absl/synchronization:thread_pool as only visible to internal
Abseil targets since it is internal-only.

Add support for the [[clang::reinitializes]] attribute.

This will be used to prevent false positives in the clang-tidy check
bugprone-use-after-move.
