LLVM Symbolizer attempt to symbolize addresses of optimized binaries reports missing line numbers for some cases. It maybe due to compiler which sometimes cannot map an instruction to line number due to optimizations. Symbolizer should handle those cases gracefully. Adding an option '--skip-line-zero' to symbolizer so as to report the nearest non-zero line number. --------- Co-authored-by: Amit Pandey <amit.pandey@amd.com>
