This is likely to be broken entirely by the recent proposals to modify
the on-disk representation of Numeric.

Rather than trying to share code, it'd likely be better to make a
separate routine that can directly compare two values in the packed
(on-disk) representation, and modify the externally-callable entry
points to use that.  That way avoids imposing constraints on how
different the packed and unpacked representations can be.
