This change introduces a check for the strtab offset to prevent llvm-objdump from crashing when processing malformed ELF files. It provide a minimal reproduce test for https://github.com/llvm/llvm-project/issues/86612#issuecomment-2035694455. Additionally, it modifies how llvm-objdump handles and outputs malformed ELF files with invalid string offsets.(More info: https://discourse.llvm.org/t/should-llvm-objdump-objdump-display-actual-corrupted-values-in-malformed-elf-files/84391) Fixes: #86612 Co-authored-by: James Henderson <James.Henderson@sony.com>
