calls.c: Use rtx_insn 

gcc/
2014-08-21  David Malcolm  <dmalcolm@redhat.com>

	* calls.c (emit_call_1): Strengthen local "call_insn" from rtx to
	rtx_insn *.
	(internal_arg_pointer_exp_state): Likewise for field "scan_start".
	(internal_arg_pointer_based_exp_scan): Likewise for locals "insn",
	"scan_start".
	(load_register_parameters): Likewise for local "before_arg".
	(check_sibcall_argument_overlap): Likewise for param "insn".
	(expand_call): Likewise for locals "normal_call_insns",
	"tail_call_insns", "insns", "before_call", "after_args",
	"before_arg", "last", "prev".  Strengthen one of the "last" from
	rtx to rtx_call_insn *.
	(fixup_tail_calls): Strengthen local "insn" from rtx to
	rtx_insn *.
	(emit_library_call_value_1): Likewise for locals "before_call" and
	"last".
