    sve: Fix fcmuo combine patterns [PR106524]

    There's no encoding for fcmuo with zero.  This restricts the combine
patterns
    from accepting zero registers.

    gcc/ChangeLog:

            * config/aarch64/aarch64-sve.md (*fcmuo<mode>_nor_combine,
            *fcmuo<mode>_bic_combine): Don't accept comparisons against zero.
