	* config/nios2/nios2.c (save_reg, restore_reg): Use plus_constant.
	Use rtx_insn * instead of rtx.
	(nios2_emit_add_constant): Use rtx_insn * instead of rtx.
	(nios2_expand_prologue, nios2_expand_epilogue): Likewise.
	(nios2_call_tls_get_addr): Likewise.
	(nios2_emit_expensive_div): Likewise.
	(nios2_emit_move_sequence): Change return type to bool.
	* config/nios2/nios2-protos.h (nios2_emit_move_sequence):
	Change return type to bool.
