Users should generally observe no difference as long as they don't use unintended option forms. Behavior changes: * `-t=d` is removed. Use `-t d` instead. * `--demangle=false` and `--demangle=0` cannot be used. Omit the option or use `--no-demangle`. Other flag-style options don't have `--no-` forms. * `--help-list` is removed. This is a `cl::` specific option. * llvm-readobj now supports grouped short options as well. * `--color` is removed. This is generally not useful (only apply to errors/warnings) but was inherited from Support. Some adjustment to the canonical forms (usually from GNU readelf; currently llvm-readobj has too many redundant aliases): * --dyn-syms is canonical. --dyn-symbols is a hidden alias * --file-header is canonical. --file-headers is a hidden alias * --histogram is canonical. --elf-hash-histogram is a hidden alias * --relocs is canonical. --relocations is a hidden alias * --section-groups is canonical. --elf-section-groups is a hidden alias OptTable avoids global option collision if we decide to support multiplexing for binary utilities. * Most one-dash long options are still supported. `-dt, -sd, -st, -sr` are dropped due to their conflict with grouped short options. * `--section-mapping=false` (D57365) is strange but is kept for now. * Many `cl::opt` variables were unnecessarily external. I added `static` whenever appropriate. Reviewed By: jhenderson Differential Revision: https://reviews.llvm.org/D105532
