[DWARF] Fix handling of .debug_aranges with -g1

Old behavior was to add to .debug_aranges only when we create a DIE. As the
result we could end up in situation where DW_AT_ranges have addresses that are
not in .debug_aranges. This has caused issues for LLDB: D136395.

Changed it to add addresses to .debug_aranges even when DIE is not created.
