The entries for deleted basic blocks won't participate in `BAT::getFallthroughsInTrace` because trace boundary is looked up by output offsets: https://github.com/llvm/llvm-project/blob/098c6dfa8157681699a71fce9e3d94515e66311f/bolt/lib/Profile/BoltAddressTranslation.cpp#L529-L540

But deleted blocks will be used in `writeBATYAML` where we lookup containing blocks by input offsets: https://github.com/llvm/llvm-project/blob/098c6dfa8157681699a71fce9e3d94515e66311f/bolt/lib/Profile/DataAggregator.cpp#L2358-L2367
