[Bug tree-optimization/25145] missed VRP opportunity

Even the simple code like:
int f(int i, int j )
{
   int k;
   k = i+ - 1;
   return k < i;
}

Does not get VRP to optimize it which means we don't do that much symbolic
ranges as we should.  From looking at things, the only time we get a symbolic
range is from scev and never make it ourselves which seems wrong.
