When LLVM is used in other projects, it may happen that global constructors will execute before the call to `ParseCommandLineOptions`. Since `OptBisect` is initialized via a constructor, and has no ability to be updated at a later time, passing `-opt-bisect-limit` to the parse function may have no effect.

To avoid this problem use a `cl::cb` (callback) to set the bisection limit when the option is actually processed.
