[AArch64] Adjust writeback in non-zero memset
This fixes an ineffiency in the non-zero memset. Delaying the writeback until the end of the loop is slightly faster on some cores - this shows ~5% performance gain on Cortex-A53 when doing large non-zero memsets. * sysdeps/aarch64/memset.S (MEMSET): Improve non-zero memset loop.
