i965: disable bounds checking on arrays with stride 0
if stride is 0 we cannot use count as max index for bounds checking, since the hardware will simply return 0 as data for indices failing bounds check. If stride is 0 any index should be valid hence simply disable bounds checking in this case. This fixes bugs introduced with e643bc5fc7afb563028f5a089ca5e38172af41a8.
