Gor Nishanov 8a7cd49d0b [Coroutines] Part14: Handle coroutines with no suspend points.
Summary:
If coroutine has no suspend points, remove heap allocation and turn a coroutine into a normal function.

Also, if a pattern is detected that coroutine resumes or destroys itself prior to coro.suspend call, turn the suspend point into a simple jump to resume or cleanup label. This pattern occurs when coroutines are used to propagate errors in functions that return expected<T>.
