    target/105753: Fix ICE in add_clobbers due to extra PARALLEL in insn.

    This patch removes the superfluous parallel in [u]divmod patterns in
    the AVR backend.  Effect of extra parallel is that add_clobbers reaches
    gcc_unreachable() because the clobbers for [u]divmod are missing.
    If an insn has multiple parts like clobbers, the parallel around the
    parts of the insn pattern is implicit.

            ([u]divmod<mode>4): Tidy code.  Use gcc_unreachable() instead of
            printing error text to assembly.
