Instrumentation passes now use attributes address_safety/thread_safety/memory_safety which are added by Clang frontend. Clang parses the blacklist file and adds the attributes accordingly. Currently blacklist is still used in ASan module pass to disable instrumentation for certain global variables. We should fix this as well by collecting the set of globals we're going to instrument in Clang and passing it to ASan in metadata (as we already do for dynamically-initialized globals and init-order checking). This change also removes -tsan-blacklist and -msan-blacklist LLVM commandline flags in favor of -fsanitize-blacklist= Clang flag. llvm-svn: 210038
