    Add SHF_COMPRESSED section decompression to gold

    This patch adds SHF_COMPRESSED section decompression to gold.

        PR gold/18321
        * compressed_output.h (decompress_input_section): Add arguments
        for ELF class, big endian and sh_flags.
        * compressed_output.cc (decompress_input_section): Likewise.
        Support the SHF_COMPRESSED section.
        * dynobj.h (Dynobj): Add elfsize and is_big_endian member
        functions.
        * plugin.h (Pluginobj): Likewise.
        * layout.cc (Layout::get_output_section_flags): Also clear the
        SHF_COMPRESSED bit.
        * object.h (Compressed_section_info): Add flag to store sh_flags.
        (Object): Add pure virtual elfsize and is_big_endian member
        functions.
        * object.cc (need_decompressed_section): Don't skip the ".zdebug"
        prefix here.
        (build_compressed_section_map): Check SHF_COMPRESSED for
        uncompressed size.  Store sh_flags in Compressed_section_info.
        Pass size, big_endian and sh_flags to decompress_input_section.
        Skip the ".debug"/".zdebug" prefix when passing section name to
        need_decompressed_section.
        (Sized_relobj_file<size, big_endian>::do_find_special_section):
        Don't check ".zdebug_*" sections.
        (Object::decompressed_section_contents): Pass ELF class, big
        endian and sh_flags to decompress_input_section.
        * reloc.cc (Sized_relobj_file<size, big_endian>::write_sections):
        Likewise.
        * testsuite/Makefile.am (check_DATA): Add
        debug_msg_cdebug_gabi.err and gdb_index_test_2_gabi.stdout.
        (MOSTLYCLEANFILES): Add debug_msg_cdebug_gabi.err and
        gdb_index_test_2_gabi.stdout.
        (debug_msg_cdebug_gabi.o): New.
        (odr_violation1_cdebug_gabi.o): Likewise.
        (odr_violation2_cdebug_gabi.o): Likewise.
        (debug_msg_cdebug_gabi.err): Likewise.
        (check_SCRIPTS): Add gdb_index_test_2_gabi.sh.
        (gdb_index_test_cdebug_gabi.o): Likewise.
        (gdb_index_test_2_gabi): Likewise.
        (gdb_index_test_2_gabi.stdout): Likewise.
        * testsuite/gdb_index_test_2_gabi.sh: New file.
        * testsuite/Makefile.in: Regenerated.
