Add .gdb_index version 7 support.
This patch adds support for .gdb_index version 7, which adds several
flag bits to the symbol index. It also fixes a problem where it did
not handle compressed debug sections correctly.
Tested with a google/gcc-4_8 branch compiler, which supports
the -ggnu-pubnames option to generate .debug_gnu_pubnames/pubtypes
tables. (We will submit that patch to GCC when stage 1 reopens.)

* gold/dwarf_reader.cc: include <utility> (for make_pair).
(Dwarf_abbrev_table::do_read_abbrevs): Check for compressed
debug sections.
(Dwarf_ranges_table::read_ranges_table): Likewise.
(Dwarf_pubnames_table::read_section): Check for GNU-style
sections, and for compressed debug sections.
(Dwarf_pubnames_table::read_header): Compute end address of table.
(Dwarf_pubnames_table::next_name): Return flag_byte. Check
for end of list by offset, not by offset == 0.
(Dwarf_info_reader::do_read_string_table): Check for compressed
debug sections.
* gold/dwarf_reader.h (Dwarf_pubnames_table::Dwarf_pubnames_table):
Initialize new data members.
(Dwarf_pubnames_table::next_name): return flag_byte.
(Dwarf_pubnames_table::end_of_table_): New data member.
(Dwarf_pubnames_table::is_gnu_style_): New data member.
* gold/gdb-index.cc (gdb_index_version): Update to version 7.
(Gdb_index_info_reader::read_pubtable): Read flag_byte.
(Gdb_index_info_reader::read_pubnames_and_pubtypes): Don't
read skeleton type unit DIEs.
(Gdb_index::add_symbol): Add flag_byte; adjust all callers.
(Gdb_index::do_write): Write flag_byte.
* gold/gdb-index.h (Gdb_index::add_symbol): Add flags parameter.
(Gdb_index::Cu_vector): Store flags along with cu indexes.
* gold/testsuite/gdb_index_test_3.sh: Allow versions 4-7.
* gold/testsuite/gdb_index_test_comm.sh: Likewise.
