      Description

      The change made by JDK-8264649 seems to break the test case compiler/eliminateAutobox/TestIntBoxing.java on 32-bit arm in fastdebug builds. This is a bit weird to me, since it looks like the change should actually fix the problem.

      The JVM crashes with:

      ACTION: main -- Failed. Unexpected exit from test [exit code: 1]
      REASON: User specified action: run main/othervm -Xbatch -XX:+IgnoreUnrecognizedVMOptions -XX:+EliminateAutoBox compiler.eliminateAutobox.TestIntBoxing

      Reverting the change done in JDK-8264649 using `$ git revert --no-commit 42f4d706` makes the problem disappear and the test doesn't crash anymore.
