RFR: 8295662: jdk/incubator/vector tests fail "assert(VM_Version::supports_avx512vlbw()) failed"

Wed Oct 19 14:15:33 UTC 2022

This patch removes the incorrectly used `evmovdqub` and uses `evmovdqul` because the former requires AVX512BW, which is unavailable on KNL settings. We have `C2_MacroAssembler::load_vector` already so we can use it here instead.

Thanks a lot.
