/* The latency of a memory load assumed by the assembly implementation
   of the mem and str functions.  Since we don't have any clue about
   where the data might be, let's assume it's in the L2 cache.  
   Assuming L3 would be too pessimistic :-)

   Some functions define MEMLAT as 2, because they expect their data
   to be in the L1D cache.  */
