Description
JDK-8269179 example shows that we don't test enough wide vectors on x64. I suggest to create new HotSpot test group for such tests and together with jdk_vector group run them with different SSE + AVX HotSpot flags combinations. For now it is: -XX:UseAVX=3 -XX:UseAVX=2 -XX:UseAVX=1 -XX:UseAVX=0 -XX:UseAVX=0 -XX:UseSSE=3 -XX:UseAVX=0 -XX:UseSSE=2 (this is minimal setting for 64 bit)
