[7u60] Request for approval: 8030059: ShouldNotReachHere error when creating an array with component type of void

[Christian Thalinger]

https://bugs.openjdk.java.net/browse/JDK-8030059

The bug was originally filed against 7u40 but turned out that we have the same problem in 8 so we pushed to 8 first:

https://bugs.openjdk.java.net/browse/JDK-8029366
http://hg.openjdk.java.net/jdk8/jdk8/hotspot/rev/b87211e33ebb

This is the request to backport to 7u60.  The review (plus the patch) for the 8 push is here:
