	* gas/config/tc-arm.c: Use arm_feature_set.
	(arm_ext_*, arm_arch_full, arm_arch_t2, arm_arch_none,
	arm_cext_iwmmxt, arm_cext_xscale, arm_cext_maverick, fpu_fpa_ext_v1,
	fpu_fpa_ext_v2, fpu_vfp_ext_v1xd, fpu_vfp_ext_v1, fpu_vfp_ext_v2):
	New variables.
	(insns): Use them.
	(md_atof, opcode_select, opcode_select, md_assemble, md_assemble,
	md_begin, arm_parse_extension, arm_parse_cpu, arm_parse_arch,
	arm_parse_fpu, arm_parse_float_abi, aeabi_set_public_attributes,
	s_arm_cpu, s_arm_arch, s_arm_fpu): Use macros for accessing CPU
	feature flags.
	(arm_legacy_option_table, arm_option_cpu_value_table): New types.
	(arm_opts): Move old cpu/arch options from here...
	(arm_legacy_opts): ... to here.
	(md_parse_option): Search arm_legacy_opts.
	(arm_cpus, arm_archs, arm_extensions, arm_fpus)
	(arm_float_abis, arm_eabis): Make const.

	* include/opcode/arm.h: Use ARM_CPU_FEATURE.
	(ARM_AEXT_*, FPU_ENDIAN_PURE, FPU_VFP_HARD): New.
	(arm_feature_set): Change to a structure.
	(ARM_CPU_HAS_FEATURE, ARM_MERGE_FEATURE_SETS, ARM_CLEAR_FEATURE,
	ARM_FEATURE): New macros.
