[Bug middle-end/25512] [4.1/4.2 Regression] Overflow not handled in ptr arithmetic folding

[rguenth at gcc dot gnu dot org]

Note that this may be INVALID if we want to treat pointer overflow as
undefined,
as the std doesn't talk about pointer overflow at all.

Using proper (unsigned) integer types for this kind of arithmetic is
recommended anyway.
