PEP 3104 says that the nonlocal and global statements should allow a
shorthand. ("global x; x = 3" == "global x = 3") This patch implements that.

Please review.

- the add_ast_fields() function seems to be added by this patch, but it 
is already in svn.

- Are 1-tuple supported?

    t = [1]
    global a, = t

I think I may have been merging add_ast_fields when I wrote the patch.

Here's a new patch that handles "global x, = (5,)". To do it, I added a
new flag* to the Global and Nonlocal AST objects that indicates whether
the value needs to be unpacked or not.

* The flag is an int. The bool AST type was removed in py3k.
