[patch, fortran, committed] Allow dumping of code in Fortran syntax tree

[Thomas Koenig]

Hello world,

I have just committed the attached patch as obvious.  No test case,
the function is only supposed to be called when debugging the
compiler itself.

Regards

        Thomas

        * dump-parse-tree.c (show_code):  Add prototype.
        (gfc_debug_code):  New function.
        (show_code_node):  Add space after SELECT TYPE.
