inlinestatic

When evaluating the sumcheck protocol - can we skip evaluation of all relations for a given row? This is purely a prover-side optimization.

When used in Chonk, the ECCVM has a large fixed size, which is often not fully utilized. If a row is completely empty, the values of z_perm and z_perm_shift will match, we can use this as a proxy to determine if we can skip Sumcheck::compute_univariate_with_row_skipping. In fact, here are several other conditions that need to be checked to see if we can skip the computation of all relations in the row.
