This CL contains the phi insertion step of the SSA construction algorithmus: The phi instructions inserted are not functional yet. Renaming is not included yet. I based it on Kevin's CL (http://codereview.chromium.org/10388161/), rebased and fixed a bug (added missing iterator.Advance()) there. It also reintroduces the Definition IL class because Phi-instructions are also definitions that are referenced by UseVal. I also added the set of immediately dominated blocks to each basic block. This will be needed for pre-order dominator-tree traversal in the renaming pass.
