示例1: checklist
/**
* A runtime guard block may have monitor stores and privarg stores along with the guard
* it self. This method will rearrange these stores and split the block, managing any
* uncommoning necessary for eventual block order.
*
* The provided block will become the privarg block, containing any privarg stores and additonal
* temps for uncommoning. It must be evaluated first. The returned block will contain monitor
* stores and the guard. If no split is required, the provided block will be returned.
*
* @param comp Compilation object
* @param block Block to manipulate
* @param cfg Current CFG
* @return The block containing the guard.
