Minor bug in int-array, long-array, float-array and double-array

[Frantisek Sodomka]

It looks that there is a bug in int-array, long-array, float-array and
double-array when creating an array using an empty sequence.

Doc:
clojure.core/int-array
([size-or-seq] [size init-val-or-seq])
Creates an array of ints

This works:
user=> (int-array 0)
#<int[] [I@11978b>
user=> (vec (int-array 0))
[]
user=> (alength (int-array 0))
0

This throws NPE:
user=> (int-array [])
java.lang.NullPointerException (NO_SOURCE_FILE:0)
user=> (long-array [])
java.lang.NullPointerException (NO_SOURCE_FILE:0)
user=> (float-array [])
java.lang.NullPointerException (NO_SOURCE_FILE:0)
user=> (double-array [])
java.lang.NullPointerException (NO_SOURCE_FILE:0)

All other possible combinations seem to work.

Thank you, Frantisek

Sorry, forgot to mention: Found when testing Clojure 1.0.0.
