`vector-count``pred?``vec_1``vec_2``···`procedureCounts the number of parallel elements in the vectors that satisfy

`pred?`, which is applied, for each index`i`in the range [0,`length`) — where`length`is the length of the smallest vector argument —, to`i`and each parallel element in the vectors at that index, in order.Examples:

(vector-count (λ (i elt) (even? elt)) '#(3 1 4 1 5 9 2 5 6)) ;=> 3

(vector-count (λ (i x y) (< x y)) '#(1 3 6 9) '#(2 4 6 8 10 12)) ;=> 2
