As far as I know, it does not work out of the box with clang-tidy. Time tracing works only if you setup a profiler singleton instance with `llvm::timeTraceProfilerInitialize`, and it is invoked from the clang driver (clang/tools/driver/cc1_main.cpp) and some other non-clang tools, but not from clang-tidy. It should be relatively easy to add, but I don't want to extend the scope of this PR.
