Maybe I need to explain why it would work in start (ramp) function. Generally, the ramp function is very small. But in case the initial_suspend of the coroutine wouldn't always suspend, the start function could be as large as the original function. In this case, it should remain the original semantics.

Comment at: llvm/lib/Transforms/Coroutines/CoroSplit.cpp:304
+        Shape.FrameTy->getTypeAtIndex(coro::Shape::SwitchFieldIndex::Resume)));
+    Builder.CreateStore(NullPtr, GepIndex);
     if (!InResume)

I am not sure if I understand your point. I think the place where the `coro.end` lives should be the right place. The common function is made.
