RFR [XS] of VM portions of JDK-8214546: Start of release updates for JDK 14

[Joseph D. Darcy]

Hello,

The time for the fork of JDK 13 approaches and therefore preparations 
for transitioning jdk/jdk to be JDK 14 are underway.

Please review the VM portions of the in-progress start of release 
updates for 14:

     http://cr.openjdk.java.net/~darcy/jdk14-fork.2/

Patches for the few VM-related changes are listed as diffs below. Builds 
and langtools aspects of this change are being reviewed separately on 
the appropriate mailing lists. Before this change is eventually pushed, 
I'll regenerate the javac --release symbol information from the latest 
JDK 13 promoted build and redo a build + test cycle to make sure no 
additional tests need to be updated, etc.

Thanks,

-Joe
