Although the type is unsafe, the count is marked `@safe`, and this use of `unsafe` results in a warning (regardless of whether strict memory safety is enabled or not). Keep emitting `unsafe` when the pointer buffer is wrapped in Optional for now however, because that is currently flagged as unsafe. rdar://162416566
