The patch in http://reviews.llvm.org/D13745 is broken into four parts:

1. New interfaces without functional changes.
2. Use new interfaces in SelectionDAG, while in other passes treat probabilities as weights.
3. Use new interfaces in all other passes.
4. Remove old interfaces.

This the first patch above.
