Goal of this change is to guarantee stable ordering of the statepoint arguments and other newly inserted values such as gc.relocates. Previously we had explicit sorting in a couple of places. However for unnamed values ordering was partial and overall we didn't have any strong invariant regarding it. This change switches all data structures to use SetVector's and MapVector's which provide possibility for deterministic iteration over them. Explicit sorting is now redundant and was removed.
