\| \| \| \| \| \| \| \| \| \|	This time, also fix the caller of AddGlue to properly handle incomplete chains. AddGlue had failure modes, but shamefully hid them from its caller. It's luck ran out.

	DAGCombine strangeness may result in multiple loads from the same offset. They both may try to glue themselves to another load. We could insist that the redundant loads glue themselves to each other, but the beter fix is to bail out from bad gluing at the time we detect it.
