RFR (XXL): 8223347: Integration of Vector API (Incubator): Hotspot and x86 backend changes

[Viswanathan, Sandhya]

Hi Vladimir and Coleen,

We are getting ready to propose to target Vector API to JDK 16. 
Please find below the updated hotspot and x86 backend changes:

Shared Hotspot:
   Full: http://cr.openjdk.java.net/~sviswanathan/VAPI_RFR/hs_webrev/webrev.01/
   Incremental: http://cr.openjdk.java.net/~sviswanathan/VAPI_RFR/hs_webrev/webrev.00-webrev.01/

X86:
   Full: http://cr.openjdk.java.net/~sviswanathan/VAPI_RFR/x86_webrev/webrev.01/
   Incremental: http://cr.openjdk.java.net/~sviswanathan/VAPI_RFR/x86_webrev/webrev.00-webrev.01/

Older webrev links for your reference:
Shared Hotspot: http://cr.openjdk.java.net/~vlivanov/panama/vector/jep338/hotspot.shared/webrev.00/
X86b backend: http://cr.openjdk.java.net/~sviswanathan/VAPI_RFR/x86_webrev/webrev.00/
To get incremental webrev, I had to do some adjustments to these to be able to apply it to the jdk tip.

Please let us know your feedback and if we have ok from you to propose to target to JDK 16. 

Best Regards,
Sandhya

Good to know that it does not mean that code is "unstable" ;)

Katya filed today new bug [1]. Please look.
