Do you think it makes sense for Type::isIncompleteType() to return

decl is a
      // forward declaration, but not a full definition (C99 6.2.5p22).
-    return !cast<TagType>(CanonicalType)->getDecl()->isDefinition();
+    TagDecl *TD = cast<TagType>(CanonicalType)->getDecl();
+    return !TD->isDefinition() || TD->isInvalidDecl();

Since this predicate is fairly low-level, I wanted to get some
