I resolved the request by using the nonstatic Profile method of the BitIntType class, but it seems it was not const qualified. I added the const qualifier to follow other similar classes. We could keep this change, or go back to the change I had. Please let me know which one the reviewers prefer. We probably need @AaronBallman and/or @erichkeane to review - seems Erich made the original BitIntType addition? Thanks
