Attached patch enables ASDL parser to construct fields in the right order.

It resolves the issue below in Parser/
# XXX can't I just construct things in the right order?

We can safely use left-recursive grammar since Parser/ implements Earley parser.

The patch doesn't affect Python-ast.[ch] as expected.

$ diff -s ~/test/Python-ast.c Python/Python-ast.c
