Use FileCheck's --implicit-check-not='ThreadSanitizer' which increases the strictness of our tests a bit. NFC. ``` CHECK: start CHECK-NOT: ThreadSanitizer CHECK: done ``` With --implicit-check-not, the above is turned into: ``` CHECK-NOT: ThreadSanitizer CHECK: start CHECK-NOT: ThreadSanitizer CHECK: done CHECK-NOT: ThreadSanitizer ``` llvm-svn: 360927
