(float*, fix*): Rewrite to match hardware; take/put
integer input/output from/to fp register instead of memory or
general register.  Delete 6 now obsolete combiner patterns.

	needs_range_function, issue_delay, and max_blockage fields.  Drop
	costexp, and busy delay fields.
	(enum operator): Add POS_MINUS_OP, EQ_OP, MIN_OP, RANGE_OP.
	(operate_exp): Implement new ops.
	(make_internal_attr): Set unsigned_p based on the value of SPECIAL.

	(write_attr_valueq): Write hex value of large constants in a comment.
	(simplify_by_exploding): Check for EXP having no EQ_ATTR expressions
	and for all values as the default.
	(find_and_mark_used_attributes): Add TERMS and NTERMS parameters.
	(max_attr_value): Allow IF_THEN_ELSE.
	(simplify_knowing, write_complex_function, extend_range): New
	functions.

	`<name>_unit_blockage' and `<name>_unit_blockage_range' functions.
	Compute max_blockage, and the needs_*_function values.
	(write_function_unit_info): Write blockage function and conflict cost
	functions using write_complex_function.  Write new function_unit_desc
	fields.
(expand_units): Use the normalized values of the

	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.

	unit_tick, unit_n_insns): New variables.
	(schedule_insns): Allocate and initialize insn_tick, insn_units, and
	insn_blockage.

	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.

From-SVN: r1951

	(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.
