Driver: Stop linking to C++ when using sanitizers on Darwin
Sanitizers on Darwin are built as dynamic libraries, not static libraries.
Sanitizers will have their C++ dependency satisfied internally (LC_LOAD_DYLIB)
in the libclang_rt dylib. As long as the sanitizers stay dynamic and not static,
linking against C++ when enabling a sanitizer becomes over linkage.

Summary:
UBSan is now used in the same way as ASan, and is supported on
OSX and on iOS simulator. At the moment ASan and UBSan can't be used
together due to PR21112, but I hope to resolve it soon by
embedding UBSan into ASan.
Test Plan: regression test suite.

Change the LC_ID_DYLIB of ASan's dynamic libraries on OS X to be set to "@rpath/libclang_rt.asan_osx_dynamic.dylib" and similarly for iossim. Clang driver then sets the "-rpath" to be the real path to where clang currently has the dylib (because clang uses the relative path to its current executable). This means if you move the compiler or install the binary release, -fsanitize=address will link to the proper library.
