This actually reverts 418120556398c01550d42500d56e6d328290185b. The original commit omits unit with all symbols inlined into current one, which leads to crash when a module using split-dwarf inlined a function from another module with mismatched split-dwarf-inlining option. This revert guarantees that DIEs are created in both DWO and the skeleton sections whenever split-dwarf is active.
