[PATCH] D31096: LTO, Support: Add a safeguard against pruning a directory that is not a cache directory.

[Peter Collingbourne via Phabricator via llvm-commits]

pcc abandoned this revision.
pcc added a comment.

Ivan suggested that we can just use a hidden directory inside the user-supplied directory as the cache directory. I like that approach better, so I'm abandoning this.
