This patch increases scatter overhead on Neoverse-V2 to 13. This benefits s128 kernel from TSVC_2 test suite. SPEC 17, RAJAPerf, and Sptter are unaffected by this patch. This patch boosts s128 kernel's performance from TSVC test suite by about 40% as this enables vectorization. Also, handle minor code refactoring for gather related part.
