Removed my comments unrelated to this PR and moved them to following merge PR which has been updated with latest code from lworld
https://github.com/openjdk/valhalla/pull/1688

I plan to conclude this merge by next week, there are some failures, if the code changes are too many then I will open seperate follow up PRs for them instead of adding them with merge.

We don't use Unsafe.putValue/getValue in VectorAPI fallback so removing them looks fine to me. 

Best Regards
