For infinite precision integer in particular you need access to the carry bit that is generated by vector artihmetic and other instruction level features.
SSE provides no mean whatsoever to obtain the carry bits when doing addition of vectors. Altivec does, however. I don't see how that changes anything with regards to the user anyway. Those are details from the internals of the 128-bit integer type.
