  [DWARFLinker] Preserve DWARF discriminators while linking (#96124)

DWARF-4 introduced DWARF discriminators but both, the classic and the
parallel DWARF linkers discarded them so far.

After applying this patch dsymutil, which uses the DWARF linkers,
correctly preserves discriminator information.
