[Bug rtl-optimization/19001] [3.4/4.0 Regression] Loops with power of two step and variable bounds not unrolled

To Zdenek and Andrew it's obvious, but maybe it's worth mentioning that the
following kind of loop, not involving explicitly power of two steps, pointers
instead, and *very* simple, is also not unrolled anymore:

int*
check(int* a, int* b)
{
 for (; a < b; ++a)
   if (*a == 1)
     return a;
 return a;
}

Maybe the Summary could be made a tad clearer
