Add a semantics test for the intrinsic function `image_status`. Add
a check and restriction on the `image` argument in `image_status`.
This check ensures that the `image` argument is a positive integer,
if the actual argument is a constant expression. The `size` argument
to the intrinsic `ishftc` is also required to be a positive integer,
so this check has also been added to that argument. A short
semantics test checking this restriction to the `size` argument
of `ishftc` has also been added.
