        * tree-vect-generic.c (expand_vector_comparison): Handle lhs being
        a vector boolean with scalar mode.
        (expand_vector_condition): Handle first operand being a vector boolean
        with scalar mode.
        (expand_vector_operations_1): For comparisons, don't bail out early
        if the return type is vector boolean with scalar mode, but comparison
        operand type is not.

        * gcc.target/i386/avx512f-pr91157.c: New test.
        * gcc.target/i386/avx512bw-pr91157.c: New test.
