Well, sort of... LLVM considers whatever you pass to
ParseCommandLineOptions to be the command line, so you can tweak it
depending on your needs.

Command-line options are used for convenience in a variety of
places... if there's some specific option that you need to modify at
runtime that can't be changed in any other way, patches to change that
are welcome.

Also, IIRC, LLVM isn't threadsafe at the moment...
