cpython-lru_cache-weakref: Python/compile.c annotate

annotate Python/compile.c @ 14178:dff22d4a48da legacy-trunk

Fix allowable node-types for assignment, need to add 'listmaker'. (This fix is a bit broken, just as the test already was: the test for testlist and listmaker are done always, whereas the test for exprlist and the actual abort() are only done if Py_DEBUG is defined. Suggestions welcome, I guess ;)
