Documentation part.
The makeinfo gcc/fortran/gfortran.texi does not seem to have any new warnings.
Is there a specific reason thy -fc-prototypes (Interoperability
Options section) is excluded from manpage?

Subject: Fortran: Add Developer Options mini-section to documentation
Separate out -fdump-* options to the new section. Sort by option name.
While there, document -save-temps intermediates.
gcc/fortran/ChangeLog:
* invoke.texi: Add Developer Options section. Move '-fdump-*'
to it. Add small examples about changed '-save-temps' behavior.
