	* config/tc-mips.c (mips_set_options): New "ase_mdmx" member.
	(mips_opts): Initialize "ase_mdmx" member.
	(file_ase_mdmx): New variable.
	(CPU_HAS_MDMX): New macro.
	(md_begin): Initialize mips_opts.ase_mdmx and file_ase_mdmx
	based on command line options and configuration defaults.
	(macro_build): Note in comment that use of MDMX in macros is
	not currently allowed.
	(validate_mips_insn): Add support for the "O", "Q", "X", "Y", and
	"Z" MDMX operand types.
	(mips_ip): Accept MDMX instructions if mips_opts.ase_mdmx is set,
	and add support for the "O", "Q", "X", "Y", and "Z" MDMX operand
	types.
	(OPTION_MDMX, OPTION_NO_MDMX, md_longopts, md_parse_option):
	Add support for "-mdmx" and "-no-mdmx" options.
	(OPTION_ELF_BASE): Move to accomodate new options.
	(s_mipsset): Support ".set mdmx" and ".set nomdmx".
	(mips_elf_final_processing): Set MDMX ASE ELF header flag if
	file_ase_mdmx was set.
	* doc/as.texinfo: Document -mdmx and -no-mdmx options.
	* doc/c-mips.texi: Likewise, and document ".set mdmx" and ".set
	nomdmx" directives.
