Do you mean you are also working on removing TYPE_IS_SIZETYPE?

I think 64-bit mode should also have this optimization enabled. XFAIL implies
the missing of this optimization is a correct behavior. But I think this is not
what I expected. So I don't think we should add XFAIL for this case. Instead I
want to add a new test case scev-5.c to cover 64-bit testing.
