[vector] Draft PR for JEP 417 support of masking in hardware

[Ningsheng Jian]

Thank you Paul for the work!

I did a diff to vectorIntrinsics branch, and found that two recent 
commits may have been missed:

https://github.com/openjdk/panama-vector/pull/139
https://github.com/openjdk/panama-vector/pull/142

Otherwise, looks good to me.

Thanks,
Ningsheng
