* config/arc/arc.c (arc_initialize_pic): Remove.

	* config/arc/arc.h (INITIALIZE_PIC): Similarly, this routine does
	nothing on any platform and is invoked by no-one, it does not even
	appear in the documentation.
	* config/sparc/sparc.h (INITIALIZE_PIC): Likewise.
	* config/sparc/sparc.c (initialize_pic): Likewise.
	(find_addr_reg): Remove this as well, no longer referenced after
	my rewrite.
