I don't see why we should rely on __builtin_memset etc. in tests. We can
just include <cstring> and use the public API.
libstdc++-v3/ChangeLog:
* testsuite/23_containers/deque/allocator/default_init.cc: Use
std::memset instead of __builtin_memset.
* testsuite/23_containers/forward_list/allocator/default_init.cc:
Likewise.
* testsuite/23_containers/list/allocator/default_init.cc:
Likewise.
* testsuite/23_containers/map/allocator/default_init.cc:
Likewise.
* testsuite/23_containers/set/allocator/default_init.cc:
Likewise.
* testsuite/23_containers/unordered_map/allocator/default_init.cc:
Likewise.
* testsuite/23_containers/unordered_set/allocator/default_init.cc:
Likewise.
* testsuite/23_containers/vector/allocator/default_init.cc:
Likewise.
* testsuite/23_containers/vector/bool/allocator/default_init.cc:
Likewise.
* testsuite/29_atomics/atomic/compare_exchange_padding.cc:
Likewise.
* testsuite/util/atomic/wait_notify_util.h: Likewise.
This fixes a race condition in the util/atomic/wait_notify_util.h header
used by several tests, which should make the tests work properly.
