Right, makes sense.  That's what I meant by "staging implementations."

Ultimately, if we bundle the dylib with the compiler, I would expect that "-faddress-sanitizer", when passed to clang for linking a framework/executable, would automatically imply -lclang_rt.asan_osx_dynamic.  I'd rather that build systems or users didn't need to know about such esoteric details, and passing "-faddress-sanitizer" to clang for linking does "the right thing".
