[issue33211] lineno and col_offset are wrong on function definitions with decorators

[Ethan Smith]

There is also a relevant mypy bug report https://github.com/python/mypy/issues/3871. This seems like a common problem for tools working on the AST. The relevant code seems to be https://github.com/python/cpython/blob/master/Python/ast.c#L1695. 

Would a possible solution be adding a decorated_lineno attribute to decorated ast nodes?
