Types composed with certain implicit record types would have their RTTI marked as hidden because the implicit record type didn't have any visibility. This manifests itself as triggering false positives from tools like clang's -fsantize=function feature. The RTTI for a function type's return type wouldn't match if the return type was an implicit record type. Patch by Stephan Bergmann! llvm-svn: 226148
