[PATCH] D22892: Codegen: MachineBlockPlacement Improve probability layout.

Added fixes for 4 affected tests. Since they weren't testing layout, I added branch weights to get the layout that was produced before. In 3 cases, this was simply equal-weighting the branches, and in the 4th the expected layout required slight biasing.
