sparc.c (arith_operand, [...]): Mark mode as unused.

	* config/sparc/sparc.c (arith_operand, const64_operand,
	const64_high_operand, arith_double_4096_operand): Mark mode as
	unused.
	(create_simple_focus_bits): Remove unused arg highest_bit_set, all
	callers changed.
	(sparc_emit_set_const64): Remove unused variable i.
	(sparc_splitdi_legitimate): Likewise for addr_part.
	(ultra_code_from_mask): Likewise for mask.
	(ultra_cmove_results_ready_p): Fixup entry modulo calc.
	(ultra_flush_pipeline): Likewise.
	(ultra_fpmode_conflict_exists): Likewise, remove unused variable
	this_type, and allow loads and stores of differing FP modes as
	they do not create a conflict.
	(ultra_find_type): Initialize fpmode to SFmode, fix
	parenthesization thinkos in large conditional.
	(ultrasparc_sched_init): Mark dump and sched_verbose as unused.
	Init free_slot_mask after ultra_cur_hist is reset, not before.
	(ultrasparc_rescan_pipeline_state): Remove unused variable ucode.
	(ultrasparc_sched_reorder): Don't bzero current pipeline state,
	use ultra_flush_pipeline instead, then re-init group pointer.
	Fix statement with no effect.  If no progress made in, and no
	instructions scheduled at all, advance to new pipeline cycle else
	we get into an endless loop.
	(ultrasparc_adjust_cost): Remove previous arg.
	* config/sparc/sparc.h (ADJUST_COST): Update to reflect that.
