  [Coroutines] Maintain the position of final suspend

Closing https://github.com/llvm/llvm-project/issues/56329

The problem happens when we try to simplify the suspend points. We might
break the assumption that the final suspend lives in the last slot of
Shape.CoroSuspends. This patch tries to main the assumption and fixes
the problem.
