[PATCH 2/2] Fortran: dump-parse-tree: Mark debug functions with DEBUG_FUNCTION

[Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>]

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

gcc/fortran/ChangeLog:

	* dump-parse-tree.cc (gfc_debug_expr): Remove forward declaration.
	(debug): Add DEBUG_FUNCTION.
	(show_code_node): Remove erroneous whitespace.

---
Regression tested on x86_64-linux, OK for trunk?
