That's a good thing. I'm really not in favor of having this cartesian explosion. If people want to run multiple configuration, then it needs to happen in some principled manner (if anything, the cmdline should be generated by a textual configuration representation, YAML or JSON or something else).

About the patch itself, LGTM. I wonder whether we should call the binary `lldb-dotest`. But I don't feel really strong about it, so go for whatever you like.
