Hidden visibility is incompatible with dllexport. Hidden and protected visibilities are incompatible with dllimport. (PlayStation uses dllexport protected.) When an explicit visibility attribute applies on a dllexport/dllimport declaration, report a Frontend error (Sema does not compute visibility).
