In LICM.cpp::cloneInstructionInExitBlock, we have a special treatment for call instructions. However, in the end, when we do `New = CallInst::Create(CI, OpBundles);`, therefore original call instruction metadata isn't cloned. We probably need to add `New->copyMetadata(*CI);` after the call instruction creation.

You can see that the 'alias.scope' and 'noalias' metadata were lost.
