        * dumpfile.c (dump_phase_enabled_p): Renamed dump_enabled_p. Update
        all callers.
	(dump_enabled_p): A new function to check if any of the dump files
	is available.
	(dump_kind_p): Remove check for current_function_decl. Add check for
	dumpfile and alt_dump_file.
	* dumpfile.h: Add declaration of dump_enabled_p.
