[GOLD] Remove addend from Local_got_entry_key
This patch removes the addend from Local_got_entry_key, which is
unnecessary now that Got_offset_list has an addend. Note that it
might be advantageous to keep the addend in Local_got_entry_key when
linking objects containing a large number of section_sym+addend@got
relocations. I opted to save some memory by removing the field but
left the class there in case we might need to restore {sym,addend}
lookup. That's also why this change is split out from the
Got_offset_list change.
PR 28192
* object.h (Local_got_entry_key): Delete addend_ field.
Adjust constructor and methods to suit.
* object.cc (Sized_relobj::do_for_all_local_got_entries):
Update key.
