[Sanitizer] Change driver behavior when linking with -fsanitize=thread and -fsanitize=memory. TSan/MSan also provide their versions of new/delete and should use the same strategy as ASan. Share the code that sets linker flags for all sanitizers. llvm-svn: 176178

If a .syms file is available alongside a sanitizer runtime, pass it to the linker via --dynamic-list instead of using --export-dynamic. This reduces the size of the dynamic symbol table, and thus of the binary (in some cases by up to ~30%). llvm-svn: 177783

Add -lrt to sanitizer link arguments. Sanitizer runtime intercepts functions from librt. Not doing this will fail if the librt dependency is not present at program startup (ex. comes from a dlopen()ed library). llvm-svn: 182645

Split ubsan runtime into three pieces (clang part): * libclang_rt-san-* is sanitizer_common, and is linked in only if no other sanitizer runtime is present. * libclang_rt-ubsan-* is the piece of the runtime which doesn't depend on a C++ ABI library, and is always linked in. * libclang_rt-ubsan_cxx-* is the piece of the runtime which depends on a C++ ABI library, and is only linked in when linking a C++ binary. This change also switches us to using -whole-archive for the ubsan runtime (which is made possible by the above split), and switches us to only linking the sanitizer runtime into the main binary and not into DSOs (which is made possible by using -whole-archive). The motivation for this is to only link a single copy of sanitizer_common into any binary. This is becoming important now because we want to share more state between multiple sanitizers in the same process (for instance, we want a single shared output mutex). The Darwin ubsan runtime is unchanged; because we use a DSO there, we don't need this complexity. llvm-svn: 177605
