S390: Optimize __memset_z196.
It turned out that an 256b-mvc instruction which depends on the result of a previous 256b-mvc instruction is counterproductive. Therefore this patch adjusts the 256b-loop by storing the first byte with stc and setting the remaining 255b with mvc. Now the 255b-mvc instruction depends on the stc instruction.
