This patch adds ThreadSanitizer support into LLDB: - Adding a new InstrumentationRuntime plugin, ThreadSanitizerRuntime, in the same way ASan is implemented. - A breakpoint stops in `__tsan_on_report`, then we extract all sorts of information by evaluating an expression. We then populate this into StopReasonExtendedInfo. - SBThread gets a new API, SBThread::GetStopReasonExtendedBacktraces(), which returns TSan’s backtraces in the form of regular SBThreads. Non-TSan stop reasons return an empty collection. - Added some test cases. Reviewed by Greg Clayton. llvm-svn: 264162
