What is the purpose of '50' here? The patch is fine for Google branch. Other tunings to think about -- I think the sharing probability should not be a fixed value -- but depending on the function's charateristics -- such as size, number of callsites etc. For instance, for small leaf comdat functions, the sharing probability will be small.
