I am not seeing one of the posts of this thread. So I'll answer 
here.

The good thing regarding the run-time overflow integral tests is 
that they are already implemented and available as efficient 
compiler intrinsics in both GCC and LLVM back-ends. It's just a 
matter of using them (and introducing the compiler switch and 
some kind of pragma syntax).
