[PATCH] Add debug msg to dump_file in add_new_function

[Tom de Vries]

Hi,

[ posted earlier as part of "Don't dump low gimple functions in gimple 
dump", https://gcc.gnu.org/ml/gcc-patches/2014-05/msg01586.html, 
currently discussed at: 
https://gcc.gnu.org/ml/gcc-patches/2015-05/msg02076.html ]

This patch adds a debug msg to dump_file in cgraph_node::add_new_function.

OK for trunk (after retesting)?

Thanks,
- Tom

	* cgraphunit.c (cgraph_node::add_new_function): Dump message on new
	function.

	* gcc.dg/gomp/notify-new-function-2.c: New test.
	* gcc.dg/gomp/notify-new-function.c: Same.
