Prevent infinite recursion in ReadDWARFDebugInfo when a DWO file contains a DW_AT_GNU_dwo_name attribute pointing to itself. We now only follow DWO links if the current CU is a skeleton CU. Issue google#344 Fixes google#476
Adds a test case simulating a self-referential DWO file to ensure recursion is handled gracefully without crashing. See google#476
