Or even simpler,
```
SmallString<128> CrashDirectory = A->getValue();
```

----------------
The other test/Driver/crash-report-* tests do "rm -rf %t" before creating the
directory. Since you're using "-p" with mkdir below, it won't fail if the dir
exists, but removing the dir before is still nice since it will clean up
temporary files from previous test runs. Without it, a new file will be added
to the dir each time the test is run, so it will grow in size over time.
