662f00ba - [lldb] Don't crash on a .gnu_debuglink section without a file name (#228116)

[lldb] Don't crash on a .gnu_debuglink section without a file name (#228116) A `.gnu_debuglink` section names the separate file that holds a binary's debug info. When the section is empty, lldb crashes while loading the binary, in both the `PECOFF` and `ELF` readers. `llvm-objcopy --only-keep-debug` produces exactly such a section when it runs on a binary that already has a debug link. On Windows CI this crashes `TestSwiftSplitDebug` in `1/10` runs. An empty or unterminated name is now treated as no debug link. New yaml tests for both formats crash without the fix and pass with it.
