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

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.

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.

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.
