Make llvm-nm -help great again Only display help from the llvm-nm category instead of all llvm options, which make it much more usable. There's still an issue with -s, which is probably a bug in llvm::cl and worth another commit.

[llvm-nm] Switch command line parsing from llvm::cl to OptTable Part of https://lists.llvm.org/pipermail/llvm-dev/2021-July/151622.html "Binary utilities: switch command line parsing from llvm::cl to OptTable" Users should generally observe no difference as long as they only use intended option forms. Behavior changes: * `-t=d` is removed. Use `-t d` instead. * `--demangle=0` cannot be used. Omit the option or use `--no-demangle` instead. * `--help-list` is removed. This is a `cl::` specific option. Note: * `-t` diagnostic gets improved. * This patch avoids cl::opt collision if we decide to support multiplexing for binary utilities * One-dash long options are still supported. * The `-s` collision (`-s segment section` for Mach-O) is unfortunate. `-s` means `--print-armap` in GNU nm. * This patch removes the last `cl::multi_val` use case from the `llvm/lib/Support/CommandLine.cpp` library `-M` (`--print-armap`), `-U` (`--defined-only`), and `-W` (`--no-weak`) are now deprecated. They could conflict with future GNU nm options. (--print-armap has an existing alias -s, so GNU will unlikely add a new one. --no-weak (not in GNU nm) is rarely used anyway.) `--just-symbol-name` is now deprecated in favor of `--format=just-symbols` and `-j`.
