- Remove obsolete checks - Fix checks that are inconsistent - Stop compiling compare256/longest_match variants that never gets called - Improve how the generic compare256 functions are handled. - Allow overriding OPTIMAL_CMP This simplifies the code and avoids having a lot of code in the compiled library than can never get executed.
