Modify Parser/asdl_c.py so that the __version__ number for Python/Python-ast.c
is specified at the top of the file. Also add a note that Python/Python-ast.c
needs to be committed separately after a change to the AST grammar to capture
the revision number of the change (which is what __version__ is set to).
