+    for (auto &I : instructions(F))
+      if (MDNode *TBAA = I.getMetadata(LLVMContext::MD_tbaa))
+        I.setMetadata(LLVMContext::MD_tbaa, nullptr);
The checking is redundant -- you can just do `I.setMetadata(LLVMContext::MD_tbaa, nullptr)` unconditionally (that should not do anything if `MD_tbaa` was not present on the instruction).
