Rong Xu 3573d8da36 [CodeGen] Peel off the dominant case in switch statement in lowering 
This patch peels off the top case in switch statement into a branch if the
probability exceeds a threshold. This will help the branch prediction and
avoids the extra compares when lowering into chain of branches.
