* mips-dis.c (no_aliases): New disassembly option flag.
	(set_default_mips_dis_options): Init no_aliases to zero.
	(parse_mips_dis_option): Handle no-aliases option.
	(print_insn_mips): Ignore table entries that are aliases
	if no_aliases is set.
	(print_insn_mips16): Ditto.
	* mips-opc.c (mips_builtin_opcodes): Add initializer column for
	new pinfo2 member and add INSN_ALIAS initializers as needed.  Also
	move WR_MACC and RD_MACC initializers from pinfo to pinfo2.
	* mips16-opc.c (mips16_opcodes): Ditto.
