CommandData breakpoint commands didn't know whether they were Python or Command line commands, so they couldn't serialize & deserialize themselves properly. Fix that. I also changed the "breakpoint list" command to note in the output when the commands are Python commands. Fortunately only one test was relying on this explicit bit of text output. llvm-svn: 282432
