[GOLD] Output_data_got tidy
Some Output_data_got methods already have support for addends, but were implemented as separate methods. This removes unnecessary code duplication. Relobj::local_has_got_offset and others there get a similar treatment. Comments are removed since it should be obvious without a comment, and the existing comments are not precisely what the code does. For example, a local_has_got_offset call without an addend does not return whether the local symbol has *a* GOT offset of type GOT_TYPE, it returns whether there is a GOT entry of type GOT_TYPE for the symbol with addend of zero. PR 28192 * output.h (Output_data_got::add_local): Make addend optional. (Output_data_got::add_local_with_rel): Likewise. (Output_data_got::add_local_pair_with_rel): Likewise. * output.cc (Output_data_got::add_local): Delete overload without addend. (Output_data_got::add_local_with_rel): Likewise. (Output_data_got::add_local_pair_with_rel): Likewise. * object.h (Relobj::local_has_got_offset): Make addend optional. Delete overload without addend later. Update comment. (Relobj::local_got_offset): Likewise. (Relobj::set_local_got_offset): Likewise.
