-- 0f6565955231dc74ebad62ef32a18c457afa2dc7 by Abseil Team <absl-team@google.com>: Document guarantee that we do not move from rvalue arguments if no insertion happens with absl::raw_hash_map::try_emplace, as done with std::unordered_map::try_emplace. PiperOrigin-RevId: 264430409 -- 292e6b9e08fa689e8400d7f2db94cbcab29d5889 by CJ Johnson <johnsoncj@google.com>: Removes use of aligned_storage in FixedArray and InlinedVector in favor of aligned char buffers. PiperOrigin-RevId: 264385559 -- aa0b19ad11ae5702022feee0e2e6434cfb28c9e9 by Derek Mauro <dmauro@google.com>: Make the unit tests for absl::any, absl::optional, and absl::variant no-ops when these types are just aliases for the corresponding std:: types. We have no way to fix standard library implementation bugs, so don't bother working around them. Also disable the corresponding exception-safety tests as well when exceptions are not enabled.
