gigi.h (create_label_decl): Adjust. 

* gcc-interface/gigi.h (create_label_decl): Adjust.
	* gcc-interface/utils.c (create_label_decl): Add GNAT_NODE parameter
	and invoke gnat_pushdecl on it.  Remove obsolete settings.
	* gcc-interface/decl.c (gnat_to_gnu_entity) <E_Label>: Adjust call to
	create_label_decl.
	* gcc-interface/trans.c (gnat_to_gnu) <N_Null): Likewise.  Ignore the
	label for debugging purposes.
