If the linked list structure used depended on the list head to know when to terminate, this would be a pretty serious bug. If try_constant_propage or try_copy_propagate make progress, inst->src[i].nr will change. This results in the foreach_in_list using a different list header on later iterations of the loop. This causes two shaders in shader-db and 9 shaders in fossil-db to change. Looking at the code changes, these are cases where there was a copy of a copy that gets propagated. The part that confuses me is the VGRF numbers involved should **not** hash to the same bucket, so it should be impossible to find the original source from the intermediate VGRF.
