According to profiling of semodule -BN, ebitmap_cardinality() is called quite often and contributes a lot to the total runtime. Cache its result in the ebitmap struct to reduce this overhead. The cached value is invalidated on most modifying operations, but ebitmap_cardinality() is usually called once the ebitmap doesn't change any more. After this patch, the time to do 'semodule -BN' on Fedora Rawhide has decreased from ~10.9s to ~8.9s (2s saved).
