I have been using CANNOT_DUMP for testing Emacs in debugging frameworks 
that are incompatible with unexec. As far as I know, this was the only 
remaining practical use for the traditional meaning of CANNOT_DUMP 
(nobody was using Emacs in CANNOT_DUMP mode for ordinary use).

As pdumper makes this usage obsolete, we should retire this obsolete use 
of CANNOT_DUMP and rename the identifier to something more reasonable 
(e.g., to PORTABLE_DUMP as Glenn suggested).
