For now only JUMP_BACKWARD is converted to ENTER_EXECUTOR, and it does not have specialization. However, in the future there might be other instructions involved, and in the scenarios where we want the base opcode, we should deopt the opcode from the VM.

Issue: Decoding instructions should handle ENTER_EXECUTOR #107265

Thanks!

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -
