[ELF] Prevent crash when reporting errors if debug line cannot be parsed LLD uses the debug info and debug line sections to determine the location of e.g. references to undefined symbols, when producing error messages. In the event that debug info was present, but debug line parsing failed for some reason, then a nullptr would end up being dereferenced by the location-lookup code.

[lld] Make tests calling llvm-ar more robust Some lit tests that call llvm-ar use the 'r' flag. If the target archive already exists and is in a corrupt state, this can cause the test to fail.
