	* arm.cc (Arm_exidx_cantunwind::do_print_to_mapfile): New method.
	(Arm_relobj::do_relocate_sections): Add new parameter for output
	file to match the parent.
	(Target_arm::scan_reloc_section_for_stubs): Use would-be final values
	of local symbols instead of input values.  Update code to track
	changes in gold::relocate_section.
	* object.cc (Sized_relobj::compute_final_local_value): New methods.
	(Sized_relobj::compute_final_local_value_internal): New methods.
	(Sized_relobj::do_finalize_local_symbols): Move code from loop
	body into private version of Sized_relobj::compute_final_local_value.
	Call the inline method.
	* object.h (Symbol_value::Symbol_value): Define destructor.  Free
	merged symbol value if there is one.
	(Symbol_value::has_output_value): New method defintiion.
	(Sized_relobj::Compute_final_local_value_status): New enum type.
	(Sized_relobj::compute_final_local_value): New methods.
	(Sized_relobj::compute_final_local_value_internal): New methods.
	* Makefile.am (check_SCRIPTS): Add arm_branch_out_of_range.sh
	and arm_cortex_a8.sh.
	(thumb_bl_out_of_range_local, arm_cortex_a8_b_cond, arm_cortex_a8_bl,
	arm_cortex_a8_blx, arm_cortex_a8_local, arm_corte_a8_local_reloc):
	New tests.
