        (Arm_relobj::~Arm_relobj): Delete object pointed by
        attributes_section_data_.
        (Arm_relobj::attributes_section_data): New method definition.
        (Arm_relobj::attributes_section_data_): New data member declaration.
        (Arm_dynobj::Arm_dynobj): Initialize attributes_section_data_.

        (Target_arm::Target_arm): Initialize attributes_section_data_.  Change
        initialization value of may_use_blx_ to false.
        (Target_arm::using_thumb2, Target_arm::using_thumb_only,
        Target_arm::may_use_arm_nop, Target_arm::may_use_thumb2_nop): Use
        object attributes to compute results instead of hard-coding.
        (Target_arm::do_attribute_arg_type, Target_arm::do_attributes_order,
        Target_arm::get_secondary_compatible_arch,
        Target_arm::set_secondary_compatible_arch
        Target_arm::tag_cpu_arch_combine, Target_arm::aeabi_enum_name,
        Target_arm::tag_cpu_name_value, Target_arm::merge_object_attributes):
        New method declarations.
        (Target_arm::get_aeabi_object_attribute): New method definition.
        (Target_arm): New enums for EABI object attribute values.

        (Arm_dynobj::do_read_symbols): Ditto.
