void	addTopLevelLoop (MachineLoop *New)
	This adds the specified loop to the collection of top-level loops.

void	removeBlock (MachineBasicBlock *BB)
	This method completely removes BB from all data structures, including all of the Loop objects it is nested in and our mapping from BasicBlocks to loops.

void	analyze (const DominatorTreeBase< MachineBasicBlock, false > &DomTree)
