From a @dblaikie review comment in https://reviews.llvm.org/D32713.
I wasn't sure whether changing the actual tables was the idea, or just simplifying the extraction.
A StringRef does take up more space, and it's common to have large numbers of directory and file entries; I don't think it's *that* big a deal, but I thought I'd get an opinion from reviewers first.
