gcc:
	* config/mips/genopt.sh, config/mips/mips-cpus.def: New files.
	* config/mips/mips-tables.opt: New file (generated).
	* config.gcc (mips*-*-*): Add mips/mips-tables.opt to
	extra_options.
	* config/mips/mips-opts.h (MIPS_ARCH_OPTION_FROM_ABI,
	MIPS_ARCH_OPTION_NATIVE): Define.
	* config/mips/mips.c (mips_cpu_info_table): Move contents to
	mips-cpus.def.
	(mips_strict_matching_cpu_name_p, mips_matching_cpu_name_p,
	mips_parse_cpu): Remove.
	(mips_cpu_info_from_opt, mips_default_arch): New.
	(mips_handle_option): Don't assert that global structures are in
	use.  Don't handle OPT_march_, OPT_mtune_ and OPT_mips here.
	(mips_option_override): Use new variables and functions to set
	state of these options.  Use strcmp to check for individual CPU
	names.
