I think literal arrays are always immutable, and one could base the
test on that.

Is such a function useful in some other context? If one has an array which is
already immutable, it can be referenced freely and copying it seems
unnecessary.

Suggestion: add a few tests to test-suite/tests/arrays.test:
(pass-if-equal "new"
#t
(array-mutable? (make-array #f '(1 2) '(3 4
(pass-if-equal "empty (two-dimensional)"
#t
(array-mutable? (array-copy #1(
(pass-if-equal
Doesn't seem there was any simple way to check this from either Scheme or C.
