Instead of creating real threads for trace tests create a new ThreadState in the main thread. This makes the tests more unit-testy and will also help with future trace tests that will need more than 1 thread. Creating more than 1 real thread and dispatching test actions across multiple threads in the required deterministic order is painful. This is resubmit of reverted D110546 with 2 changes: 1. The previous version patched ImitateTlsWrite to not expect ThreadState to be allocated in TLS (the CHECK failed for the fake test threads). This added an ugly hack into production code and was still logically wrong because we imitated write to the main thread TLS/stack when we started the fake test thread (which has nothing to do with the main thread TLS/stack). This version uses ThreadType::Fiber instead of ThreadType::Regular for the fake threads. This naturally makes ThreadStart skip obtaining stack/tls and imitating writes to them. 2. This version still skips the tests on Darwin and PowerPC to be on the safer side. Build bots reported failures for PowerPC for the previous version.
