[patch, fortran, committed] Add a few more debug functions

[Thomas König]

Hello world,

I have just committed this patch as obvious to make debugging
a bit easier. No user impact, the code compiles :-)

Regards

        * dump-parse-tree.c (debug):  Add for symbol_attribute *,
        symbol_attribute and gfc_ref * arguments.
