FYI this change had some pretty significant impact on compile-time (https://llvm-compile-time-tracker.com/compare.php?from=4718ec01669b01373180f4cd1256c6e2dd6f3999&to=f748e92295515ea7b39cd687a718915b559de6ec&stat=instructions) and code size (https://llvm-compile-time-tracker.com/compare.php?from=4718ec01669b01373180f4cd1256c6e2dd6f3999&to=f748e92295515ea7b39cd687a718915b559de6ec&stat=size-text). Is that expected?
