All the previous refactoring to make the assertion fast paths smaller and faster also allows us to implement the fast paths just with thread-local and atomic variables, without full mutexes. However, the performance overhead of thread-safe assertions is still significant for single threaded usage: | slowdown | Debug | Release | |-----------|--------:|--------:| | fast path | 1.04x | 1.43x | | slow path | 1.16x | 1.22x | Thus, we don't make the assertions thread-safe by default, and instead provide a build-time configuration option that the users can set to get thread-safe assertions. This commit is functional, but it still needs some follow-up work: * We do not need full seq_cst increments for the atomic counters, and using weaker ones can be faster. * We brute-force updating the reporter-friendly totals from internal atomic counters by doing it everywhere. We should properly trace where this is needed instead. * Message macros (`INFO`, `UNSCOPED_INFO`, `CAPTURE`, etc) are not made thread safe in this commit, but they can be made thread safe in the future, by building on top of this work. * Add more tests, including with thread-sanitizer, and compiled examples to the repository. Right now, these changes have been compiled with tsan manually, but these tests are not added to CI. Closes #2948
