In theory a DWARF producer could produce any structure. Clang and Swift only
produce this form. I was trying to come up with a very simple cycle detection
here. My thinking was that if the parent is the CU and the specification isn't
the current DIE this is not a cycle, but thinking about it again, there still
could be a larger cycle. I'll rework this to use a visited set.
