Add a flag -fthread-sanitizer. This flag enables ThreadSanitizer instrumentation committed to llvm as r150423. The patch includes one test for -fthread-sanitizer and one similar test for -faddress-sanitizer. This patch does not modify the linker flags (as we do it for -faddress-sanitizer) because the run-time library is not yet committed and it's structure in compiler-rt is not 100% clear. The users manual wil be changed in a separate commit. llvm-svn: 151846

Add -fsanitize=<sanitizers> argument to driver and frontend, and add -fno-sanitize=<sanitizers> argument to driver. These allow ASan, TSan, and the various UBSan checks to be enabled and disabled separately. Right now, the different modes can't be combined, but the intention is that combining UBSan and the other sanitizers will be permitted in the near future. Currently, the UBSan checks will all be enabled if any of them is; that will be fixed by the next patch. llvm-svn: 167411
