     * Unconditional branch, 32-bit offset.
     *
     * The branch distance is a signed code-unit offset, which we need to
     * double to get a byte offset.
     *
     * Unlike most opcodes, this one is allowed to branch to itself, so
     * our "backward branch" test must be "<=0" instead of "<0".
