asyncio REPL doesn't allow using asynchronous comprehensions outside of async func. Same behavior can also be observed when using `ast.PyCF_ALLOW_TOP_LEVEL_AWAIT` flag in `compile()`

Example with `async for`:
>>> async def async_gen():
...     for x in range(5):
...         yield await asyncio.sleep(1, x)
... 
>>> [x async for x in async_gen()]
  File "<console>", line 0
SyntaxError: asynchronous comprehension outside of an asynchronous function


Example with `await`:
>>> [await asyncio.sleep(1, x) for x in range(5)]
  File "<console>", line 0
SyntaxError: asynchronous comprehension outside of an asynchronous function
