cpython-lru_cache-weakref: Modules/arraymodule.c annotate

annotate Modules/arraymodule.c @ 14499:7f23ec5cd9ca legacy-trunk

General cleanup in preparation for a bugfix: removed unused code, useless declarations, added some comments where I had to think too hard to understand what was happening, and changed the primary internal get/set functions to assert they're passed objects of the correct type instead of doing runtime tests for that (it's an internal error that "should never happen", so it's good enough to check it only in the debug build).
