COMMON: Allow construction of Arrays of non-copyable members

Although the previous count-constructor would never make a copy of
a member at runtime, Array<T>::reserve *may* copy-construct, so
the compiler would forbid creation of arrays of NonCopyable objects
even when the array was created only once and then never resized
(and thus never actually tried to perform a copy-construction).
