linkage_section_type when its scan of the heap encounters non-marked
words that are not "hidden" by a non-marked vector header.

complains on stderr about any invalid linkage section types, object
types, etc.  If the GC_Debug flag is set, verify_heap is called by the
garbage-collect primitive to scan maximal heap.
