array-map and hash-map differ in handling of keys comparing identical but not equal

Description

user=> (let [a (array-map Double/NaN 1)] (assoc a (key (first a)) "foo")) {NaN 1, NaN "foo"} user=> (let [a (hash-map Double/NaN 1)] (assoc a (key (first a)) "foo")) {NaN "foo"}

Approach: Array-map's comparison skips identity-check and always delegates to .equals calls. The attached patch alignes array-map behaviour with hash-map by doing the appropriate pointer checks before delegating to .equals
