Export of internal Abseil changes -- c99f979ad34f155fbeeea69b88bdc7458d89a21c by Derek Mauro <dmauro@google.com>: Remove a floating point division by zero test. This isn't testing behavior related to the library, and MSVC warns about it in opt mode. PiperOrigin-RevId: 285220804 -- 68b015491f0dbf1ab547994673281abd1f34cd4b by Gennadiy Rozental <rogeeff@google.com>: This CL introduces following changes to the class FlagImpl: * We eliminate the CommandLineFlagLocks struct. Instead callback guard and callback function are combined into a single CallbackData struct, while primary data lock is stored separately. * CallbackData member of class FlagImpl is initially set to be nullptr and is only allocated and initialized when a flag's callback is being set. For most flags we do not pay for the extra space and extra absl::Mutex now. * Primary data guard is stored in data_guard_ data member. This is a properly aligned character buffer of necessary size. During initialization of the flag we construct absl::Mutex in this space using placement new call. * We now avoid extra value copy after successful attempt to parse value out of string. Instead we swap flag's current value with tentative value we just produced. PiperOrigin-RevId: 285132636 -- ed45d118fb818969eb13094cf7827c885dfc562c by Tom Manshreck <shreck@google.com>: Change null-term* (and nul-term*) to NUL-term* in comments PiperOrigin-RevId: 285036610 -- 729619017944db895ce8d6d29c1995aa2e5628a5 by Derek Mauro <dmauro@google.com>: Use the Posix implementation of thread identity on MinGW.

ON_CALL/EXPECT_CALL do a sufficient job here. PiperOrigin-RevId: 288386509 -- fdec6f40293d5883220f1f0ea1261f7c5b60a66e by Derek Mauro <dmauro@google.com>: Upgrade MacOS tests to use Bazel 2.0.0 PiperOrigin-RevId: 288373298 -- 465865c4123e9481ab50ea0527e92b39519704dd by Derek Mauro <dmauro@google.com>: Changes to support GCC 9 * Fix several -Wredundant-move warnings * Remove FlatHashMap.Any test, which basically doesn't work on any platform any more (see https://cplusplus.github.io/LWG/lwg-active.html#3121) * Fix a constant sign-compare warning * Conditionally compile out the PoisonHash test which doesn't build PiperOrigin-RevId: 288360204 -- 57c4bb07fc58e7dd2a04f3c45027aab5ecaccf25 by Andy Soffer <asoffer@google.com>: Deflaking MockingBitGen test. Because MockingBitGen can return random values, it is inherently flaky. For log-unifrom, 2040 is a common enough value that tests failed unreasonably frequently. Replacing it with a significantly larger value so as to be much less common. 50000 is a good choice because it is (tied for) the least likely to occur randomly from this distribution, but is still in the distribution. PiperOrigin-RevId: 288360112 -- 86f38e4109899d972de353b1c556c018cfe37956 by Matt Calabrese <calabrese@google.com>: Remove construction tests for the internal `CompressedTuple<std::any>` instantiation. This was not guaranteed to work for the reasons that `std::tuple<std::any>` copy construction does not actually work by standard specification (some implementations introduce workarounds for this). In GCC9, `CompressedTuple<std::any>` and `std::tuple<std::any>` both fail for the same reasons, and a proper "fix" requires updating `std::any`, which is out of our control.
