I agree with your math.  I think leaving `Begin` and `End` as `uint32_t` makes sense; I doubt this would be the only weak link if someone tried to put 2^32 operands on a call, and even if we were to run on a platform with an odd pointer size, I'd expect sizeof(BundleOpInfo) to be a multiple of it by virtue of the Tag pointer field.
