[PATCH 1/2] Fortran: dump-parse-tree attribs: fix unbalanced braces [PR109624]

[Bernhard Reutner-Fischer via Gcc-patches]

From: Bernhard Reutner-Fischer <al...@gcc.gnu.org>

gcc/fortran/ChangeLog:

        PR fortran/109624
        * dump-parse-tree.cc (debug): New function for gfc_namespace.
        (gfc_debug_code): Delete forward declaration.
        (show_attr): Make sure to print balanced braces.

---
(gdb) call debug(gfc_current_ns)

Namespace: A-H: (REAL 4) I-N: (INTEGER 4) O-Z: (REAL 4)
procedure name = fmodule
  symtree: 'C_ptr'       || symbol: 'c_ptr'
    type spec : (UNKNOWN 0)
    attributes: )

There is an open brace missing after "attributes: "

Regression tested on x86_64-linux, OK for trunk?
