This is x86 specific, and adds statefulness to MachineModuleInfo. Instead of explicitly tracking this, infer if we need to declare the symbol based on the reference previously inserted. This produces a small change in the output due to the move from AsmPrinter::doFinalization to X86's emitEndOfAsmFile. This will now be moved relative to other end of file fields, which I'm assuming doesn't matter (e.g. the __morestack_addr declaration is now after the .note.GNU-split-stack part) This also produces another small change in code if the module happened to define/declare __morestack_addr, but I assume that's invalid and doesn't really matter.
