[PATCH] D21814: clang-rename: support multiple renames with one invocation

I'm a bit confused.

On one hand, I want to use tooling::CommonOptionsParser to parse the options, which needs a cl::OptionCategory as a parameter.

On the other hand, I want to parse the options, based on that I'll know what subcommand was requested, and then I can choose the right option category. Based on the above example, I want to use an option category that recognizes -oldname when "rename-all" is used, and I want an other option category that recognizes -offset" when "rename-at" is used.

I sense a chicken-and-egg problem, the argument of CommonOptionsParser needs the category, but I'll only know the correct category after I called CommonOptionsParser. Or is there a way out of this? ;-)
