[analyzer] Check for returning null references in ReturnUndefChecker.
Officially in the C++ standard, a null reference cannot exist. However,
it's still very easy to create one:
int &getNullRef() {
int *p = 0;
return *p;
}
We already check that binds to reference regions don't create null references.
This patch checks that we don't create null references by returning, either.
