Anton Korobeynikov d84847ac9d Reland Allow normal function results of @yield_once coroutines (#71645) 
* Allow normal function results of @yield_once coroutines

* Address review comments

* Workaround LLVM coroutine codegen problem: it assumes that unwind path never returns.
This is not true to Swift coroutines as unwind path should end with error result.
