    Description

      All instances of type Register exhibit UB in the form of wild pointer (including null pointer) dereferences. This isn't very hard to fix: we should make Registers pointers to something rather than aliases of small integers.

      JDK-8276563 fixed this for Aarch64 while this bug should fix it for x86.
