// This class is intended to be the container for Instructions.  This container
// owns the instructions that are in it.  When removing an Instruction from the
// list, the caller is assuming responsibility for deleting the storage.
//
// TODO: Because there are a number of other data structures that will want
// pointers to instruction, ownership should probably be moved to the module.
// Because of that I have not made the ownership passing in this class fully
// explicit.  For example, RemoveFromList takes ownership from the list, but
// does not return an std::unique_ptr to signal that.  When we fully decide on
// ownership, this will have to be fixed up one way or the other.
