Introduce a distinct type for :pep:`492` coroutines; add types.CoroutineType,
inspect.getcoroutinestate, inspect.getcoroutinelocals; coroutines no longer
use CO_GENERATOR flag; sys.set_coroutine_wrapper works only for 'async def'
coroutines; inspect.iscoroutine no longer uses collections.abc.Coroutine,
it's intended to test for pure 'async def' coroutines only; add new opcode:
GET_YIELD_FROM_ITER; fix generators wrapper used in types.coroutine to be
instance of collections.abc.Generator; collections.abc.Awaitable and
collections.abc.Coroutine can no longer be used to detect generator-based
coroutines--use inspect.isawaitable instead.
