	  (Stub_table::empty): Look at both reloc_stubs_ and cortex_a8_stubs_
	  to determine if the table is empty.
	  (Stub_table::has_been_changed, Stub_table_set_has_been_changed):
	  Remove.
	  (Stub_table::add_reloc_stub): Define method in class definition

	  (Stub_table::do_addralign_): Return address alignment in the
	  (Stub_table::do_reset_address_and_file_offset): Define method in
	  class definition instead of declaring it there.  Set current data
	  size to be the data size of the previous pass.
	  (Stub_table::set_final_data_size): Use current data size as the
	  final data size.
	  (Stub_table::relocate_stub): Change parameter type of stub from
	  Reloc_stub pointer to Stub pointer.
	  (Stub_table::addralign_, Stub_table::has_been_changed_): Remove.
	  (Stub_table::Cortex_a8_stub_list): New typedef.
