config/xtensa: Use rtx_insn and rtx_code_label

gcc/
	* config/xtensa/xtensa-protos.h (xtensa_emit_loop_end): Strengthen
	first param from rtx to rtx_insn *.
	* config/xtensa/xtensa.c (struct machine_function): Likewise for
	field "set_frame_ptr_insn".
	(xtensa_expand_compare_and_swap): Strengthen locals "csloop" and
	"csend" from rtx to rtx_code_label *.
	(xtensa_expand_atomic): Likewise for local "csloop".
	(xtensa_emit_loop_end): Strengthen param "insn" from rtx to
	rtx_insn *.
	(xtensa_call_tls_desc): Likewise for return type and locals
	"call_insn", "insns".
	(xtensa_legitimize_tls_address): Likewise for local "insns".
	(xtensa_expand_prologue): Likewise for locals "insn", "first".
