valhalla/valhalla reparenting to jdk10/hs

[Karen Kinnear]

Folks,

We are about to reparent http://hg.openjdk.java.net/valhalla/valhalla
from jdk9 to http://hg.openjdk.java.net/jdk10/hs

Yes, that is explicitly the jdk10 hotspot repository since we have done significant
post-jdk9 hotspot changes with which we want to merge.

Yesterday I took a snapshot of valhalla/valhalla to ensure no work is lost.
If you have anything you want to save as a patch or want to take your own snapshot
please do so.

I will send an email update when the reparenting and merging of current value types
changes are ready. To minimize downtime, we have been working on the merge in
a temporary local repository.

thanks,
Karen
