void llvm::InstCombineWorklist::AddInitialGroup	(	Instruction *const *	List,
		unsigned	NumEntries

AddInitialGroup - Add the specified batch of stuff in reverse order. which should only be done when the worklist is empty and when the group has no duplicates.

AddUsersToWorkList - When an instruction is simplified, add all users of the instruction to the work lists because they might get more simplified now.
