-   f() used to get optimized to an infinite loop by tree-vrp, because
-   j is assumed to be non-negative.  Even though the conversion from
-   unsigned to signed has unspecified results if the expression value
-   is not representable in the signed type, the compiler itself (e.g.,
-   the Ada front end) depends on wrap-around behavior.  */
