[PATCH GCC]Reduce compilation time for IVOPT by skipping cost computation in use group

Hi, Quite lot of time is used when IVOPT computes cost for pairs. As a matter of fact, some pairs are very similar to each other, and we can abstract and compute cost only once for these pairs. This is a patch doing so, the idea is skipping cost computation for sub-uses in each group, of cour
