David Callahan 919a213064 [ADCE] Add control dependence computation

Summary:
This is part of a serious of patches to evolve ADCE.cpp to support
removing of unnecessary control flow.

This patch adds the ability to compute control dependences using
the iterated dominance frontier. We extend the liveness propagation
to alternate between data and control dependences until convergences.

Modify the pass manager intergation to compute the post-dominator tree
needed for iterator dominance frontier.

We still force all terminators live for now until we add code to
handlinge removing control flow in a later patch.

No changes to effective behavior with this patch
