	* arm.h: New enums for EABI object attribute tags and values.

gold/ChangeLog
	* arm.cc (attributes.h): New include.
	(Arm_relobj::Arm_relobj): Initialize attributes_section_data_.
	(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.

	attributes_section_data_.
	(Arm_dynobj::attributes_section_data): New method definition.
	(Arm_dynobj::attributes_section_data_): New data member declaration.
	(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

	(Arm_dynobj::do_read_symbols): Ditto.
	(Target_arm::do_finalize_sections): Merge attributes sections from
	input.  Check for BLX use after attributes section merging.
	Fix __exidx_start and __exidx_end visibility.  Create an
	.ARM.attributes section if necessary.
