    vect: Also cost gconds for scalar [PR118211]

    Currently we only cost gconds for the vector loop while we omit costing
    them when analyzing the scalar loop; this unfairly penalizes the vector
    loop in the case of loops with early exits.

    This (together with the previous patches) enables us to vectorize
    std::find with 64-bit element sizes.
