  Log Message:
  -----------
  [DomTree] Replace ChildrenGetter with GraphTraits over GraphDiff.

Summary:
This replaces the ChildrenGetter inside the DominatorTree with
GraphTraits over a GraphDiff object, an object which encapsulated the
view of the previous CFG.
This also simplifies the extentions in clang which use DominatorTree, as
GraphDiff also filters nullptrs.
