Well, it's not a properly formatted patch, or course, but it is all of the
code that's needed.

No, this isn't for llvm-gcc _per_se_.  It's for anyone that wants to register
some passes as command line options but not others.  It could be used
by a wide variety of tools.  One of those could be llvm-gcc, but that's for
someone else to do.

Because this isn't targeted only at gcc.  I don't even have a modified 
llvm-gcc.  I'm putting this to use in another tool.
