error: 5: global variable initializer must be a constant expression
3 errors
Add test for variables of type void. We should, of course, detect this and report an error.

Remove void from the list of opaque types. `void` behaves differently from opaque types in several situations, such as function return types, and errors involving `void` should not call it an opaque type. I've fixed all the places where we relied on `isOpaque` to return catch void types.
