[Bug tree-optimization/19790] equality not noticed when signedness differs.

Still doesn't work.  You need to replace one line for the test case of comment
#0 though, because the tree optimizers are now smart enough to see that (i/32)
is always 0.  So replace 

   for (i = 0; i <= 10; i++)

with

   for (i = 0; i <= 320; i++)

and you still get the missed optimization.
