[patch, fortran, committed] Remove duplicate output of save attribute

[Thomas Koenig]

Hello world,

I just committed the attached patch as obvious, simple and having
no user impact), as r15-7575.

Previously, a dump looked like

    attributes: (VARIABLE IMPLICIT-SAVE BIND(C) SAVE-IMPLICIT)

and now it is

    attributes: (VARIABLE IMPLICIT-SAVE BIND(C))

Best regards

        Thomas

Remove double output of attr->save.

In the recent patch for dumping all attributes, there were
duplicates for attr->save, which is output via gfc_code2string
previously. This patch removes that double output.

gcc/fortran/ChangeLog:

        * dump-parse-tree.cc (show_attr): Remove double output
        of attr->save.
