[DWARFLinker] Allow emission of repeated identical discriminators (#98255) 
Zero discriminator for each row in the line-table to correctly emit
repeated but identical discriminators.

Without this patch line-tables like

    0x0000000100003bac     12     20      0   0            65       0
    0x0000000100003bb4     12     30      0   0            65       0
    0x0000000100003bbc     12     28      0   0            65       0

get falsely linked as

    0x0000000100003bac     12     20      0   0            65       0

[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.
