lgtm with the test CHECK change



================
Comment at: llvm/test/tools/llvm-reduce/fail-file-open.test:5
+
+# CHECK: llvm-reduce: {{.*}}.NotAFileInTestingDir: error: Could not open input file: No such file or directory
----------------
is this error message cross platform? for example, I see
```
# Don't check the OS-dependent message "No such file or directory".
```
in llvm/test/tools/llvm-objdump/invalid-input.test

I think everything up to the `error:` is good enough. The main thing is that it doesn't crash.
