[PATCH] D26634: Make block placement determinisatic

[Benjamin Kramer via llvm-commits]

Note that SetVector::remove is O(n) whereas SmallPtrSet::erase was O(1). I guess it doesn't matter too much, land this now to make codegen deterministic again. If perf issues arise we can come up with a more clever way (e.g. sorting by block number before iterating over the set).
