    mempool: use cache for frequently updated stats
    
    When built with stats enabled (RTE_LIBRTE_MEMPOOL_STATS defined),
    the performance of mempools with caches is improved as follows.
    
    When accessing objects in the mempool, either the put_bulk and put_objs or
    the get_success_bulk and get_success_objs statistics counters are likely
    to be incremented.
    
    By adding an alternative set of these counters to the mempool cache
    structure, accessing the dedicated statistics structure is avoided
    in the likely cases where these counters are incremented.
    
    The trick here is that the cache line holding the mempool cache structure
    is accessed anyway, in order to access the 'len' or 'flushthresh' fields.
    Updating some statistics counters in the same cache line has lower
    performance cost than accessing the statistics counters in the dedicated
    statistics structure, which resides in another cache line.
    
    mempool_perf_autotest with this patch shows the following improvements in
    rate_persec.
    
    The cost of enabling mempool stats (without debug) after this patch:
    -6.8 % and -6.7 %, respectively without and with cache.
