  Log Message:
  -----------
  Don't warn about missing DWO files when converting mach-o files. (#152598)

Apple uses the DW_AT_GNU_dwo_id for non split DWARF cases. Any compile
units with this attribute would cause many warnings to be emitted:

"warning: Unable to retrieve DWO .debug_info section for"

This patch fixes the DWARFTransformer to not look for skeleton compile
unit in mach-o based binaries and adds a unit test.
