This make non-await list comprehension coroutine-code-objects as well:
https://bugs.python.org/issue41218
import ast
import inspect
cell = '[x for x in l]'
code = compile(cell, "<>", "exec", flags=getattr(ast,'PyCF_ALLOW_TOP_LEVEL_AWAIT', 0x0))
inspect.CO_COROUTINE & code.co_flags == inspect.CO_COROUTINE # this is now TRUE.
This leads to weird things in Jupyter/IPython when we try to detect wether a block of code is, or os not async.
