When emitting metadata for a Swift-defined @objc protocol that has provided a specific Objective-C name (e.g., via @objc(renamed)), mangle such protocols using their Objective-C names so they can be found at runtime. Only do this for metadata, because doing it anywhere else would cause an ABI break. Fixes rdar://problem/47877748.
