Jan Kratochvil 927aa2e778 DWARF-5: .debug_names index consumer
Some testcases needed to be updated as they were missing
.debug_aranges.  While that does not matter for no-index (as GDB
builds the mapping internally during dwarf2_build_psymtabs_hard) and
neither for .gdb_index (as GDB uses that internally built mapping
which it stores into .gdb_index) it does matter for .debug_names as
that simply assumes existing .debug_aranges from GCC.
