Subject: [PATCH] Adjust test of missing declarators to cover only cases that
 are legal.

Previously, it included some instances that violate the standard constraint that a declaration must declare a declarator, a tag, or an enum constant. As of commit f263066f616, this constraint is now enforced, so those cases would (properly) give errors.
