AArch64: Optimize memset
Improve small memsets by avoiding branches and use overlapping stores. Use DC ZVA for copies over 128 bytes. Remove unnecessary code for ZVA sizes other than 64 and 128. Performance of random memset benchmark improves by 24% on Neoverse N1. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
