	* config/pa/pa.md (type): Add sibcall and sh_func_adrs insn types.
	(in_branch_delay): Don't allow sibcall or sh_func_adrs insns.
	(in_nullified_branch_delay): Likewise.
	(in_call_delay): Likewise.
	Define delay for sibcall insns.  Adjust Z3 and Z4 insn reservations for
	new types.  Add opaque cond to mark all calls, sibcalls, dyncalls and
	the $$sh_func_adrs call as variable.  Update type of sibcalls and
	$$sh_func_adrs call.
	* config/pa/pa.c (pa_adjust_insn_length): Revise to return updated
	length instead of adjustment.  Handle negative and undefined call
	adjustments for insn_default_length.  Remove adjustment for millicode
	insn with unfilled delay slot.
	(pa_output_millicode_call): Update for revised millicode length.
	* config/pa/pa.h (ADJUST_INSN_LENGTH): Revise to set LENGTH.
