In previous versions of LLVM, I believe you could get some sort of Node 
object from DominatorTree and then use a method to get the children of 
the Node (and then use a method of the Node to get the BasicBlock held 
in that Node).

However, I don't see such a method in the doxygen documentation for 
mainline LLVM.

Does this method still exist?  My own code (written for LLVM 2.6) 
traverses the dominator tree top-down as well, and I'll probably need to 
port this code to LLVM 2.7 and beyond.
