* 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/c-mips.texi: Likewise, and document ".set mdmx" and ".set
nomdmx" directives.
