still need a new loop-preheader if the predecessor has multiple
successors. See bug: LICM/2003-02-27-PreheaderProblem.ll

* Significant changes to the preheader insertion pass:
...
- Now we perform loop exit-block splitting to ensure exit blocks are
always dominated by the loop header.
- We now preserve dominance frontier information
- This fixes bug: LICM/2003-02-26-LoopExitNotDominated.ll
