      When running jtreg test
      compiler/parsing/TestMissingSafepointOnTryCatch.java
      on macOS aarch64 with ubsan-enabled binaries, we see the following issue :

      src/hotspot/share/ci/ciTypeFlow.cpp:505:36: runtime error: load of value 4294967295, which is not a valid value for type 'ciTypeFlow::Cell'
      UndefinedBehaviorSanitizer:DEADLYSIGNAL
      UndefinedBehaviorSanitizer: nested bug in the same thread, aborting.

      The printed value is 0xFFFFFFFF.
