more cpython inconsistencies with global statements

[15r10nk]

I already reported some examples in #369 where monty reports errors for valid python code.

This issue is a collection of multiple code samples with similar issues with global-statements.

code:

async def name_0():
    lambda: name_2
    global name_2
    (name_2 := 0)

monty:

name 'name_2' is used prior to global declaration

python:
no exception

---

async def name_1():
    lambda: name_4
    global name_4
    for name_4 in 0:
        pass

monty:

name 'name_4' is used prior to global declaration

python:
no exception

---

def name_4():
    try:
        lambda: name_5
        global name_5
    except:
        pass
    finally:
        name_5 = 0

monty:

name 'name_5' is used prior to global declaration

python:
no exception

---

def name_2():

    async def name_4():
        name_3

    global name_3

    def name_3():
        pass

monty:

name 'name_3' is used prior to global declaration

python:
no exception

---

async def name_3():
    try:
        lambda: name_1
    except:
        pass
    finally:
        global name_1
        import name_1

monty:

name 'name_1' is used prior to global declaration

python:
no exception

---

def name_0():
    import name_0 as name_3

    global name_3

monty:

name 'name_3' is used prior to global declaration

python:
no exception

---

def name_5():
    try:
        pass
    except name_1:
        pass
    else:
        global name_1

monty:

name 'name_1' is used prior to global declaration

python:
no exception

---

async def name_0():
    lambda: name_2
    global name_2
    (name_2 := 0)

monty:

name 'name_2' is used prior to global declaration

python:
no exception
