The intent for `@inline(always)` is to act as an optimization control. The user can rely on inlining to happen or the compiler will emit an error message. Because function values can be dynamic (closures, protocol/class lookup) this guarantee can only be upheld for direct function references. In cases where the optimizer can resolve dynamic function values the attribute shall be respected. rdar://148608854
