Add a command-line option to your pass using the LLVM command-line
library: http://llvm.org/docs/CommandLine.html. You can find examples
in the LLVM source; the inlining optimization pass (in
lib/Transforms/IPO, I believe) does this.
If you add command-line options using this library, they get registered
when loaded into opt and bugpoint.
