[ARC] DWARF emitting cleanup.

The use of CFA_FRAME_BASE_OFFSET and ARG_POINTER_CFA_OFFSET macros

Remove them.

	* config/arc/arc-protos.h (arc_decl_pretend_args): Remove.
	* config/arc/arc.c (arc_decl_pretend_args): Likewise.
	* config/arc/arc.h (CFA_FRAME_BASE_OFFSET): Likewise.
	(ARG_POINTER_CFA_OFFSET): Likewise.
