Pass CLOCK to schedule_insn.
	Compute the tail in the scheduling loop, not before it.
	Enable the stall code that advances the insn queue.
	Select the insn to schedule and block others with schedule_select.
	(adjust_priority): Renamed from launch_link.
	(schedule_insn): Renamed from launch_links.
(insn_queue): Use INSN_QUEUE_SIZE.

(insn_units, insn_blockage, insn_tick, unit_last_insn,
	unit_tick, unit_n_insns): New variables.
	(schedule_insns): Allocate and initialize insn_tick, insn_units, and
	insn_blockage.
	(insn_unit, blockage_range, clear_units, prepare_unit, schedule_unit,
	actual_hazard_this_instance, actual_hazard, potential_hazard,
	schedule_select): New functions.
	(schedule_block): Add dependencies to force insns to remain in order
	at the end of a block rather than relying on having the scheduler
	issue them in priority order.
(insn_cost): Add LINK and USED parameters.  All callers
	changed.  Supply an ADJUST_COST interface.
	(insn_cost): Make a dependence from a USE insn free.
	(priority): Clear the link cost adjustment bits.

	(write_units): Add blockage_function, blockage_range_function,
	max_blockage and max_issue_delay fields to struct function_unit_desc.
	Drop max_busy_cost field.  Write #defines for min/max blockage,
	issue delay, multiplicity, and simultaneity and for BLOCKAGE_BITS
	and INSN_QUEUE_SIZE.
	(main): Compute the new values.

	attribute, set length to 1, and fix output template to work
	properly with delay slots.

	these attributes are useless.  All references deleted.
	(call define delay): Use "in_branch_delay" as the condition since
	"call" delay slots and unconditional "branch" delay slots allow the
	same type of insns.

	(branch define delay): Do not define an annul-if-true delay slot.
	It is useless for an unconditional branch.
