bpo-31241: Fix AST node position for list and generator comprehensions. (GH-10633) 
The lineno and col_offset attributes of AST nodes for list comprehensions,
generator expressions and tuples are now point to the opening parenthesis or
square brace. For tuples without parenthesis they point to the position
of the first item.

bpo-18407: ast.c uses Py_ssize_t for asdl_seq_LEN() iterator (GH-10655) 
When iterating using asdl_seq_LEN(), use 'Py_ssize_t' type instead of
'int' for the iterator variable, to avoid downcast on 64-bit platforms.

_Py_asdl_int_seq_new() now also ensures that the index is greater than
or equal to 0.
