There are severe problems here.

LOAD_ATTR_PROPERTY takes a func_version cache entry an an fget cache entry, which need to be cross-checked (fget->func_version == func_version) but a single uop cannot reference two cache entries.

The immediate fix (after rearranging the cache entries) is to load fget onto the stack. However, this isn't safe, because it will break when DEOPT_IF() jumps back to the unspecialized opcode (since the stack is different).

Moreover, I needed to disable two assertions from the code generator. It's possible there's a better way, but I'd have to think, and it's not worth it unless we solve the other problem.

This draft PR just exists to find out what else CI finds.
