Sema: Allow inout-to-pointer conversions for pointers to arrays.

We need to admit a potential inout-to-pointer conversion even if the inout references an array, because we can have pointers to arrays. Add a short-circuit so that array-to-pointer conversions always beat inout-to-pointer conversions; both solutions could otherwise be considered valid for an UnsafePointer<Void>, and passing a pointer to the array reference rather than to the array data would be very bad.
