[PATCH, PR43920, 9/9] Cross-jumping - Allow both directions.

Allow crossjumping in both directions. Crossjump was assumed to be symmetric, and therefore only applied on edges e1,e2 and not on e2,e1. Now given both the fallthru fix and the regnotes fix, crossjumping is not symmetrical anymore, and we allow both directions (but not by testing twice). Thanks,
