e41bc94bb1 Explicitly pass -tailcallopt=false to these tests so that they 
work as intended no matter what the default setting of that
option is.

ab63152871 - CodeGenPrepare does not split loop back edges but it only knows about back edges of single block loops. It now does a DFS walk to find loop back edges. 
- Use SplitBlockPredecessors to factor out common predecessors of the critical edge destination. This is disabled for now due to some regressions.
