fab8596459 compute dominator tree children in a deterministic order that does not depend
on the address of BasicBlock objects in memory.  This eliminates stuff like this:

 Inorder Dominator Tree:
   [1]  %entry
     [2]  %loopentry
-      [3]  %loopexit
       [3]  %no_exit
-        [4]  %endif
         [4]  %then
+        [4]  %endif
+      [3]  %loopexit
       [3]  %return

eae45cf44b The recalclulate method was a nasty hack that was once used by the -cee pass,
which never worked itself.  The cee pass still doesn't work, but it doesn't use
this method anymore anyway, so eliminate the method.

16addf87bf Completely rewrite domset, idom, and domtree implementation. Now it is based
on the algorithm for directly computing immediate dominators presented in this
paper:

  A Fast Algorithm for Finding Dominators in a Flowgraph
  T. Lengauer & R. Tarjan, ACM TOPLAS July 1979, pgs 121-141.

This _substantially_ speeds up construction of all dominator related information.
Post-dominators to follow.

b884f597d6 Rework dominator interfaces to handle changes in the post-dominance
construction.  Now there may be multiple root blocks, and null is a
special node used to mark the "virtual" exit node of a CFG.

4e4caeffbd Fix a nasty problem with dominance calculation for unreachable blocks.
If we had a CFG that look like Entry -> B, Unreachable -> B, then we would
not correctly determine that Entry dominated B, because Entry did not
apparently dominate "unreachable".  This patch fixes this by making the entry
node dominate all blocks, including unreachable ones.
