Then the `ThreadName` field will lose `const`-ness, and I will also need to 
call `llvm::get_thread_name` in the constructor body, not the member 
initialization list. Would that be OK?

+    for (const auto &TTP : ThreadTimeTraceProfilerInstances) {
+      writeMetadataEvent("thread_name", TTP->Tid, TTP->ThreadName);
