  Log Message:
  -----------
  [GlobalISel] Enable usage of BranchProbabilityInfo in IRTranslator.

We weren't using this before, so none of the MachineFunction CFG edges had the
branch probability information added. As a result, block placement later in the
pipeline was flying blind.

This is enabled only with optimizations enabled like SelectionDAG.
