        Description

        vectorIntrinsics crashes with

        # Internal Error (/home/katya/work/JavaSE/Hotspot/ws/git/panama-vector/open/src/hotspot/share/prims/vectorSupport.cpp:173), pid=32306, tid=32328

        when running with DeoptimizeALot flag.

        The failed list of tests:

         jdk/incubator/vector/Byte128VectorTests.java
         jdk/incubator/vector/Byte256VectorTests.java
         jdk/incubator/vector/Byte64VectorTests.java
         jdk/incubator/vector/DoubleMaxVectorTests.java
         jdk/incubator/vector/Int128VectorTests.java
         jdk/incubator/vector/Long256VectorTests.java
         jdk/incubator/vector/Short256VectorTests.java
         jdk/incubator/vector/Short64VectorTests.java
         jdk/incubator/vector/ShortMaxVectorTests.java


        To reproduce run on of above tests with "-Xcomp -XX:CompileThreshold=100 -XX:+UnlockExperimentalVMOptions -XX:+DeoptimizeALot"

        vectorIntrinsics contains the fix for JDK-8263125 "During deoptimization vectors should reassign scalarized payload after all objects are reallocated.".
        So this is new issue.
