The intent of the original regex doesn't work if, for example, the last RUN line was a pipe and FileCheck is in the next RUN line. See for example [`function-specialization3.ll`](https://github.com/llvm/llvm-project/blob/a7c2ce6009a8034ebbf718c12a6e56c085036b57/llvm/test/Transforms/FunctionSpecialization/function-specialization3.ll). To fix this we just replace the redirerect stdout to `/dev/null` with `cat /dev/null`, which works because it's effectively a no-op command that can be piped to or run standalone. Tracking issue: llvm#147390
