Two Shenandoah hs_err for build 25.171-b10

[Aleksey Shipilev]

Jerven had replied to Zhengyu with hs_errs, the meat in both hs_errs is:

#  Internal Error (shenandoahHeapRegion.cpp:153), pid=16296, tid=0x00007e8ad98da700
#  fatal error: Disallowed transition from Collection Set to Pinned
#

I believe we have seen and fixed this, transitions from CSet -> Pinned should be allowed and go to
pinned_cset, and handled correctly by GC, starting from:
  http://hg.openjdk.java.net/shenandoah/jdk8u/hotspot/rev/cd4a36a9153b

Jerven, are you running builds from Fedora? I think those are way too old, before that changeset
landed. Unless you are using Rawhide, you might want try to replicate this on our sh/jdk8 nightly
builds:
