     Value *Object = getUnderlyingObject(SomePtr);
-    if (isWritableObject(Object) && isThreadLocalObject(Object, CurLoop, DT))
+    bool SafeToInsertStore = TTI->isSingleThreaded() || SingleThread;
+    if ((isWritableObject(Object) &&
----------------
These checks should be in isThreadLocalObject(). If there is only a single thread, then the object is always thread-local. Your current code incorrectly skips the writability check.
