  "message": "[IR] Replace blockaddress refcount with single flag (#138239)\n\nBasicBlock currently has a blockaddress refcount. However,\nblockaddresses are uniqued, which means that there can only be a single\nblockaddress for a given BasicBlock. Prior to #137958 there were some\nedge case exceptions to this, but now it always holds. As such, replace\nthe refcount with a single flag.\n\nAs we\u0027re now just tracking two bits, I\u0027ve dropped the BasicBlockBits\nstructure, as I found it more annoying than useful (esp with the weird\nAIX workarounds). Instead handle the subclass data the same way we do in\nOperators.",
