…tdResponse context sourcekitd_variant_t is only safe to use while the sourcekitd_response_t it was retrieved from is still alive, so keep a strong reference to SourceKitdResponse (the Swift wrapper of sourcekitd_response_t) in each Variant (the Swift wrapper of sourcekitd_variant_t).
…wrapper These were recently added to support returning the SyntaxTree in the bytetree from SourceKit but were never added in SwiftLang (the Swift layer wrapping SourceKit).
