Successful broadcasting by comparison operators depends on operand order

[cguenthner]

(require '[clojure.core.matrix :as m])

(m/set-current-implementation :vectorz)

(def vect (m/array [1 0]))
(def mat (m/array [[0 0] [1 1]]))

(m/eq mat vect) ;; => [[0 1] [1 0]]
(m/eq vect mat) ;; java.lang.IllegalArgumentException
                ;; Can't broadcast Matrix with shape [2,2] to shape: [2]

The above exception does not occur with the ndarray core.matrix implementation. With vectorz, it occurs with at least some of the other comparison operators (e.g. ne, gt) but not with at least some of the other arithmetic operators (e.g. add).
