What is '(array nil) suposed to mean?

It's the type of arrays with element type nil.

These arrays are specialized to hold nothing at all.
Weird, but since (upgraded-array-element-type nil) is required
to be nil, the type has to exist.

It's probably a spec bug that this is the case.  There's
a note, :allow-nil-arrays, that should be attached to all
tests involving this type.  Go ahead and disallow tests
with this note for gcl if you'd like.
