What's the difference between

(define_expand "call"
  [(call (match_operand 0 "" "")
	 (match_operand 1 "" "")
   (clobber (reg:SI 17))]
  ...)

and

(define_expand "call"
  [(parallel[(call (match_operand 0 "" "")
		   (match_operand 1 "" "")
	     (clobber (reg:SI 17))])]
  ...)

?  What if they were (define_insn) instead?
