llvm/test/tools/llvm-readobj/ELF/symbol-shndx.test

## Show that llvm-readobj prints symbol shndxes correctly, for valid indexes,
## invalid indexes (i.e. section indexes that don't correspond to a real
## section), reserved values and processor/os-specific index values, for both GNU
## and LLVM styles.
