  Log Message:
  -----------
  Add support for verifying .debug_names in split DWARF for CUs and TUs. (#101775)

This patch fixes .debug_names verification for split DWARF with no type
units. It will print out an error for any name entries where we can't
locate the .dwo file. It finds the non skeleton unit and correctly
figures out the DIE offset in the .dwo file. If the non skeleton unit is
found and yet the skeleton unit has a DWO ID, an error will be emitted
showing we couldn't access the non-skeleton compile unit.
