We exit to the outer for ( ; ; ) loop so that proofSet.reducePower() runs right away. Retrying via the inner loop is hopeless because this kind of error can't be caused by random GPU memory corruption like a verification error might be.

Proof generation can fail in two different ways. If residue corruption happens in memory before CRC generation, then the proof will generate but fail validation. If residue corruption happens any time after CRC generation,
CRCErroris raised before a proof is even generated.CRC errors correctly reduce proof power when loading saved state in
ProofSet::effectivePower, but not in proof generation, where they currently crash the process. We should handle both validation failures and CRC errors during proof generation in the same way via power reduction.
