◆ addSegment()

LoadCommand & Object::addSegment	(	StringRef	SegName,
		uint64_t	SegVMSize )

Creates a new segment load command in the object and returns a reference to the newly created load command.

The caller should verify that SegName is not too long (SegName.size() should be less than or equal to 16).
