92e1bd6dc9e64163659028b640427d6d8573e41c by Abseil Team <absl-team@google.com>:

Don't enable ABSL_HAVE_STD_IS_TRIVIALLY_ASSIGNABLE with MSVC when used with nvcc.

With nvcc on Windows __has_trivial_assign(int) is false; that leads to a failure of the check in is_trivially_copy_assignable. A better solution would probably be to use the std-provided check in this case, but that seems like a more intrusive change.

Remove hashtablez_force_sampling from the open-source release.
This should not have been released. It is internal-only and not portable.

Fixes https://github.com/abseil/abseil-cpp/issues/268
