This modifies the ClangImporter to introduce an opaque placeholder representation for forward declared Objective-C interfaces and protocols when imported into Swift. In the compiler, the new functionality is hidden behind a frontend flag -enable-import-objc-forward-declarations, and is on by default for language mode >6. The feature is disabled entirely in LLDB expression evaluation / Swift REPL, regardless of language version.
