If we know
x == Cand havex++, we can set it tox == C + 1, etc.A risk when computing this is that we might end up doing
x++from0 to 1 to 2 to 3 and so forth, until we reach some high limit. Add a
mechanism to stop such incrementing after a linear amount of work.
This is necessary to compute loop overflows.
