clang-p2996/llvm/test/Transforms/PreISelIntrinsicLowering/objc-arc.ll
Akira Hatanaka 1fe8993ad8 [ObjC][ARC] Replace uses of ObjC intrinsics that are arguments of 
operand bundle "clang.arc.attachedcall" with ObjC runtime functions

The existing code only handles the case where the intrinsic being
rewritten is used as the called function pointer of a call/invoke.
