Hmm, the regex changes were made in https://github.com/llvm/llvm-project/commit/6d8e5c968538eff2c024d46d5715de0828a69407 by Chris Bieneman and reviewed by Aaron in https://reviews.llvm.org/D119362. It looks like those regex changes need to be preserved. It seems that script could use an update. Perhaps follow up with Chris?
