That sounds surprisingly reasonable idea for signeds. Less so for unsigneds though. Has there been any architecture doing anything like that?

I can not name an ISA with such instructions out of my head.

As for unsigned integers, as I mentioned in the other comment, we probably need two separate instruction sets for "wrapping" and NaN-able operations on unsigned integers.
