Well, they were previously declared & defined in
src/backend/catalog/index.c - that's where the location is coming from
(and where they still are defined). And they're currently only used to
implement the index validation scans, which requires the validation scan
to decode item pointers stored in the tuplesort presented to it.
I'm happy to move them elsewhere, but I'm not sure there's really a good
location. I guess we could move them to itemptr.h - but they're not
really something particularly generally usable.
