Igor Laevsky 48c396748c [RS4GC] Use SetVector/MapVector instead of DenseSet/DenseMap to guarantee stable ordering
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.
