IIUC these options actually aren't mutually exclusive.
We can easily provide a single `(t)emacs` executable which at startup
will:
- look for a valid dump in the big static `dump` array.
- if not found look for a valid dump in a particular ELF section.
- if not found, look for a valid dump at the end of the `emacs` binary.
- if not found, look for a dump as a separate file at some standard
  location (starting with ~/.emacs.d/<magicid>.dump, say).
- as support a "--preload <foo>.dump" command-line option.
