When one side of an Elvis operator can only be `null`, and the entire Elvis operator expression cannot be `null`, this implies that the opposite side of the Elvis operator cannot be `null`. Add such implications to the Elvis exit node of the DFA. This helps smart-casting of variables used within long Elvis operator chains. #KT-49249 Fixed
