Fix request approved.

Fix Request This regression manifests as intermittent compiler crashes when running a JCK test and therefore needs to be fixed in JDK 13 for JCK compliance reasons. The fix is low risk (it just cleanly backs out JDK-8173196). The fix has been reviewed by Aleksey Shipilev. http://cr.openjdk.java.net/~thartmann/8229219/webrev.00/

Summary: This first showed up with JDK 13 b31 because the JCK version was updated to JCK 13 b11. Using that JCK version, I could reproduce the issue with earlier JDK builds and trace it back to changeset jdk-13-1206 which only includes the fix for JDK-8173196. I've verified with many runs that this change indeed introduced (or triggered) the crash. The original fix for JDK-8173196 (JDK-8087341) already had a bug tail and was backed out in JDK 9 (JDK-8173195). It was then re-implemented and pushed to JDK 13 b24. I propose to back it out again for JDK 13 and re-implement in JDK 14.

ILW = P1 because it's a JCK test failure
