I've merged the HookManager into the PassBuilder type. To rendezvous the PB with plugins, it is now able to call a well-known function `extern "C" void RegisterPluginPasses(PassBuilder &)` on the loaded objects. Plugins get to register callbacks there.

A linked-in Polly will not use this mechanism though, which is why I'm invoking it directly in opt's NewPMDriver as a demonstration (other tools will do the same).
