config/microblaze/microblaze.c: Use rtx_insn and rtx_code_label

gcc/
	* config/microblaze/microblaze.c (microblaze_call_tls_get_addr):
	Strengthen return type and local "insns" from rtx to rtx_insn *.
	(microblaze_legitimize_tls_address): Likewise for local "insns".
	(microblaze_block_move_loop): Strengthen local "label" from rtx
	to rtx_code_label *.
	(microblaze_expand_prologue): Strengthen two locals named "insn"
	from rtx to rtx_insn *.
	(microblaze_asm_output_mi_thunk): Likewise for local "insn".
	(microblaze_expand_divide): Likewise for locals "jump", "cjump",
	"insn".  Strengthen locals "div_label", "div_end_label" from rtx
	to rtx_code_label *.
