Bradley Smith 3e03fb9d20 [SCEV] Improve Scalar Evolution's use of no {un,}signed wrap flags ...

In a case where we have a no {un,}signed wrap flag on the increment, if
RHS - Start is constant then we can avoid inserting a max operation bewteen
the two, since we can statically determine which is greater.

This allows us to unroll loops such as:

 void testcase3(int v) {
   for (int i=v; i<=v+1; ++i)
     f(i);
 }
