-; Check the scenario where we have an unknown Stride, which happens to also be
-; the loop iteration count, so if we specialize the loop for the Stride==1 case,
-; this also implies that the loop will iterate no more than a single iteration,
-; as in the following example: 
-;
-;       unsigned int N;
-;       int tmp = 0;
-;       for(unsigned int k=0;k<N;k++) {
-;         tmp+=(int)B[k*N+j];
-;       }
-;
-; We check here that the following runtime scev guard for Stride==1 is NOT generated:
-; vector.scevcheck:
-;   %ident.check = icmp ne i32 %N, 1
-;   %0 = or i1 false, %ident.check
-;   br i1 %0, label %scalar.ph, label %vector.ph
-; Instead the loop is vectorized with an unknown stride.
