Sometimes, the Swift frontend and Clang disagrees in whether a target supports a sanitizer. This is mostly because most of these checks are happening in the Swift driver and not in the frontend. This PR makes sure we do not add the sanitizer when it is not supported to avoid compilation failures. This can happen in tests or other cases when we use swift-frontend diractly. rdar://177233134
