We would previously drop the COMDAT on the thunk we generated when replacing a function body with the forwarding thunk. This would result in a function that may have been multiply emitted and multiply merged to be emitted with the same name without the COMDAT. This is a hard error with PE/COFF where the COMDAT is used for the deduplication of Value Witness functions for Swift. llvm-svn: 358728
