	* reorg.c (fill_simple_delay_slots): Always try to fill empty
	delay slots with insns from beyond the delay insn, even if
	optimize_skip was attempted.
	(fill_simple_delay_slots): When filling with insns from after the
	delay insn, make sure to always account for sets and references
	in the delay insn.

	* pa.md (call_value+1): For non-dynamic calls, use the "call"
	attribute, set length to 1, and fix output template to work
	properly with delay slots.

	* pa.md (address and use_call_clobbered attributes): Deleted,
	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.
	(in_call_delay conditional): Deleted.
	(branch define delay): Do not define an annul-if-true delay slot.
	It is useless for an unconditional branch.
	(all delay branch conditionals): Make sure "call", "dyncall", "multi",
	and "milli" insns are explicitly disallowed in delay slots.

	* pa.c (output_mul_insn): Delete nop after branch in template,
	conditionally emit a nop if the delay slot was not filled. (via %#)

	without a frame pointer.
