No, because it would have already been too late. SuspendExpr returns the result of __builtin_coro_resume(awaiter.await_suspend().address()), which is different from the result of awaiter.await_suspend().
We need to be able to control the placement of awaiter.await_suspend(), which is why I had to break up the AST at that boundary.
