Ignore unwinding edges when checking for unconditional recursion The unconditional recursion lint determines if all execution paths eventually lead to a self-recursive call. The implementation always follows unwinding edges which limits its practical utility. For example, it would not lint function `f` because a call to `g` might unwind. It also wouldn't lint function `h` because an overflow check preceding the self-recursive call might unwind: ```rust pub fn f() { g(); f(); } pub fn g() { /* ... */ } pub fn h(a: usize) { h(a + 1); } ``` To avoid the issue, assume that terminators that might continue execution along non-unwinding edges do so.
