-    QLibraryPrivate: Actually merge load hints
-
-    Or old and new load hints in mergeLoadHints() instead of just storing
-    new ones. Andjust QLibraryPrivate::setLoadHints() to handle objects
-    with no file name differently and just set load hints directly.
-
-    Mention that load hints are merged once the file name is set
-    in the documentation for QLibrary::setLoadHints().
-
-    Add a regression test into tst_qfactoryloader.
-
-    Update and extend tst_QPluginLoader::loadHints() to take into account
-    load hints merging.
-
-    Fixes: QTBUG-114480
