Some behavior changes: * `-t=d` is removed. Use `-t d` instead. * one-dash long options like `-all` are supported. Use `--all` instead. * `--all=0` or `--all=false` cannot be used. (Note: `--all` is silently ignored anyway) * `--help-list` is removed. This is a `cl::` specific option. Nobody is likely leveraging any of the above. Advantages: * `-t` diagnostic gets improved. * in the absence of `HideUnrelatedOptions`, `--help` will not list unrelated options if linking against libLLVM-13git.so or linker GC is not used. * Decrease the probability of cl::opt collision if we do decide to support multiplexing Note: because the tool is so simple, used more for forensics instead of a building tool, and its long options are unlikely used in one-dash form, I just drop the one-dash form in this patch.
