https://bugs.openjdk.java.net/browse/JDK-8223262

Added missing checks for pending exception.
Fix was reviewed by Tom R. and Gilles D.  and pushed into jvmci-8 by Doug S.

I tested it with hs-tier4 and hs-tier6-graal where we had the problem. AOT compilation does not crush now but there are 
still test failures caused by  JDK-8220623 which will be fixed later.
