[8u] Pick up 8u222-b10 to sh/jdk8u

[Aleksey Shipilev]

Upstream aarch64-port/jdk8u-shenandoah had published July CPU, 8u222-b10, let's pick that up. All
repositories are simple pickups, only hotspot repo needs a merge.

hotspot changesets:
  http://cr.openjdk.java.net/~shade/shenandoah/merges/jdk8-8u222-b10/changesets.txt

hotspot webrev:
  http://cr.openjdk.java.net/~shade/shenandoah/merges/jdk8-8u222-b10/webrev.01/

Testing: hotspot_gc_shenandoah {fastdebug,release}
