With this patch (which I just checked in), the cgraph dump looks like
_ZN4llvm21SymbolTableListTraitsINS_10BasicBlockENS_8FunctionEE21transferNodesFromListERNS_12ilist_traitsIS1_EENS_14ilist_iteratorIS1_EES8_/3692
(void llvm::SymbolTableListTraits<ValueSubClass,
ItemParentClass>::transferNodesFromList(llvm::ilist_traits<NodeTy>&,
llvm::ilist_iterator<NodeTy>, llvm::ilist_iterator<NodeTy>) [with ValueSubClass
= llvm::BasicBlock; ItemParentClass = llvm::Function]) @0x7f75f3a373d8

So I don't know why LTO is still turning it into a local symbol.
Changing component back to ipa.
