Point at return type when it influences non-first `match` arm When encountering code like ```rust fn foo() -> i32 { match 0 { 1 => return 0, 2 => "", _ => 1, } } ``` Point at the return type and not at the prior arm, as that arm has type `!` which isn't influencing the arm corresponding to arm `2`.
