A `@convention(block)` closure in Swift is completely compatible with Objective-C and does not need to be wrapped in a `__SwiftValue` box for use. Previously, it was bridged verbatim when appearing by itself, but could end up boxed when it went through array bridging. The test verifies that: * Objective-C does not see a `__SwiftValue` box * Swift `type(of:)` does not see a `__SwiftValue` box * Objective-C can actually call the closure Resolves rdar://138132321
