Mark deleted variables as used about vulture HOT 3 CLOSED

Thanks for the report @sshishov! I agree that del a should mark the a variable as used.

Here is a little test case for this:

def foo(a):
    del a
    return 1

foo(2)

To implement this, one would need to count Name(id='a', ctx=Del()) in the abstract syntax tree as a usage of variable a. Pull requests welcome :-)
