[RewriteStatepointsForGC] Workaround a lack of determinism in visit order
The visit order being used in the base pointer inference algorithm is currently non-deterministic. When working on http://reviews.llvm.org/D12583, I discovered that we were relying on a peephole optimization to get deterministic ordering in one of the test cases.
This change is intented to let me test and land http://reviews.llvm.org/D12583. The current code will not be long lived. I'm starting to investigate a rewrite of the algorithm which will combine the post-process step into the initial algorithm and make the visit order determistic. Before doing that, I wanted to make sure the existing code was complete and the test were stable. Hopefully, patches should be up for review for the new algorithm this week or early next.
