[PATCH] D19421: [RewriteStatepointsForGC] Stabilise rematerialization order

[Igor Laevsky via llvm-commits]

So what do you think? Basically we will consume twice as much memory for sustaining order via SetVector/MapVector. And since we only need stable order in certain points and not during whole pass run, I think it's fine to keep explicit sorting. We should probably hoist such code into a clear helper function though.
