Thanks! This looks good to me, with the note about factoring out the duplicated 
logic addressed, Would you factor out that logic into a static function and 
update phabricator summary to be a commit message. Then I will commit!



================
Comment at: lib/StaticAnalyzer/Checkers/RetainCountChecker.cpp:3971
+    const ArgEffect *AE = CalleeSideArgEffects.lookup(idx);
+    if (AE && *AE == DecRef && Ty.getAsString().substr(0, 4) == "isl_")
+      state = setRefBinding(state, Sym, 
RefVal::makeOwned(RetEffect::ObjKind::Generalized, Ty));
----------------
Can you factor out the logic that looks whether the type name starts with 
"isl_" to a static function that types a type and is called something 
'isGeneralizedObjectRef"? This will avoid duplicating the logic twice here and 
will also give us a single place to update when we add an attribute indicating 
that a type is reference counted.
