[Bug c++/19437] wrong warning when assigning negative value to int

         int val = i ? i : -1;

we convert it to unsigned because it gets promoted to unsigned because i is unsigned and then there is 
an implicit cast to int. so the type of "i ? i : -1" is unsigned and there is an implicit cast to int.
