Log:
[ASan] Link with the dynamic runtime on OS X
This patch changes the behavior of the -fsanitize=address flag, making it use the dynamic runtime library (libclang_rt.asan_osx_dynamic.dylib) instead of the static one. It also drops the CoreFoundation dependency, since the dynamic runtime doesn't need it.
