Misleading comments of SplitBlockAndInsertIfThenElse in BasicBlockUtils.h

The comments of SplitBlockAndInsertIfThenElse say the SplitBefore instruction will stay in the old block.
But according to the implementation(split the block at SplitBefore by using splitBasicBlock), the SplitBefore will be moved to the new block.

This patch fixes the comments.
