+                    SourceMgr::DK_Note,
+                    "Prefix " + MatchedPrefix + " only occurs in a LABEL check, "
+                    "this is probably not what you want");
----------------
This implies that your check is per prefix.  FileCheck can be run with multiple prefixes at the same time, and I don't think there should be a warning unless none of the prefixes have non-label directives.
