When the user defines _GLIBCXX_USE_CXX11_ABI=0 to force the pre-c++11 ABI, numpy.h assumes that is_trivially_copyable is available.
It is not necessarily the case. This patch uses clang's feature detection instead.
The workaround is for certain libstdc++ versions, so the test should target these particular versions.
* Using new smart_holder::reclaim_disowned in smart_holder_type_caster for unique_ptr.
* Systematically renaming was_disowned to is_disowned (because disowning is now reversible: reclaim_disowned).
* Systematically renaming virtual_overrider_self_life_support to trampoline_self_life_support (to reuse existing terminology instead of introducing new one).
* Systematically renaming test_class_sh_with_alias to test_class_sh_trampoline_basic.
* Adding a Trampolines and std::unique_ptr section to README_smart_holder.rst.
* MSVC compatibility.
* Porting subset of absltest code from reproducer provided by @elkhrt. Baseline for debugging ASAN heap-use-after-free.
* Moving Py_DECREF to resolve ASAN heap-use-after-free failure.
* Fixing trivial formatting issue.
* Workaround for clang 3.6 and 3.7.
It was only useful for easily harvest this from the GitHub Actions CI results, mostly out of curiosity:
52 C++ function argument 1 is evaluated first.
90 C++ function argument 2 is evaluated first.
These results came for the final CI run for PR #2936; that PR has nothing else to do with the results.
Pushing directly. This tiny change is not worth a PR.

* Adding PyGILState_Check() in object_api<>::operator().
* Enabling PyGILState_Check() for Python >= 3.6 only.
Possibly, this explains why PyGILState_Check() cannot safely be used with Python 3.4 and 3.5:

* Adding simple micro benchmark.
* Reducing test time to minimum (purely for coverage, not for accurate results).
* Fixing silly oversight.
* Minor code organization improvement in test.
* Adding example runtimes.
* Removing capsys (just run with `-k test_callback_num_times -s` and using `.format()`.
* Adding test_class_sh_disowning.
* Fixing minor namespace naming inconsistency between test_class_sh_*.cpp files.
* Replacing py::overload_cast with plain cast for C++11 compatibility.
* Accommodate that the C++ order of evaluation of function arguments is unspecified.
* Adaption of PyCLIF virtual_py_cpp_mix test.
* Removing ValueError: Ownership of instance with virtual overrides in Python cannot be transferred to C++. TODO: static_assert alias class needs to inherit from virtual_overrider_self_life_support.
* Bringing back ValueError: "... instance cannot safely be transferred to C++.", but based on dynamic_cast<AliasType>.
* Fixing oversight: adding test_class_sh_virtual_py_cpp_mix.cpp to cmake file.
* clang <= 3.6 compatibility.
* Fixing oversight: dynamic_raw_ptr_cast_if_possible needs special handling for To = void. Adding corresponding missing test in test_class_sh_virtual_py_cpp_mix. Moving dynamic_raw_ptr_cast_if_possible to separate header.
* Changing py::detail::virtual_overrider_self_life_support to py::virtual_overrider_self_life_support.
* Initial version of virtual_overrider_self_life_support (enables safely passing unique_ptr to C++).
* Clang 3.6, 3.7 compatibility.
* Adding missing default constructor.
* Restoring test for exception for the case that virtual_overrider_self_life_support is not used.
* Fixing oversight: Adding missing holder().ensure_was_not_disowned().
* Adding unit tests for new `struct smart_holder` member functions.
* Moving virtual_overrider_self_life_support to separate include file, with iwyu cleanup.
* Use correct duration representation when casting from datetime.timdelta to std::chrono::duration
* When asserting datetime/timedelta/date/time we can equality-compare whole objects
* shared_ptr<bool> vptr_deleter_armed_flag_ptr (instead of unique_ptr), to fix heap-use-after-free bug.
* Fixing generated by some compilers in the pybind11 CI suite.
