xxxx-xx-xx  Claudiu Zissulescu  <claziss@synopsys.com>

	* config/arc/arc-protos.h (make_pass_arc_ifcvt): Declare.
	(make_pass_arc_predicate_delay_insns): Likewise.
	* config/arc/arc.c (class pass_arc_ifcvt): Reformat text, add gate
	method, remove clone.
	(class pass_arc_predicate_delay_insns): Likewise.
	(arc_init): Remove registering of ARC specific passes.
	* config/arc/t-arc (PASSES_EXTRA): Add arc-passes.def.
	* config/arc/arc-passes.def: New file.
