    gold: Get alignment of uncompressed section from ch_addralign

    The ELF compression header has a field (ch_addralign) that is set to
    the alignment of the uncompressed section. This way the section itself
    can have a different alignment than the decompressed section.  Update
    decompress_input_section to get alignment of the decompressed section
    and use it when merging decompressed strings.

        PR binutils/23919
        * merge.cc (Output_merge_string<Char_type>::do_add_input_section):
        Get addralign from decompressed_section_contents.
        * object.cc (build_compressed_section_map): Set info.addralign.
        (Object::decompressed_section_contents): Add a palign
        argument and store p->second.addralign in *palign if it isn't
        NULL.
        * object.h (Compressed_section_info): Add addralign.
        (section_is_compressed): Add a palign argument, default it
        to NULL, store p->second.addralign in *palign if it isn't NULL.
        (Object::decompressed_section_contents): Likewise.
        * output.cc (Output_section::add_input_section): Get addralign
        from section_is_compressed.
