[PATCH] D78501: Add a facility to get system cache directory and use it in clangd

[Sam McCall via Phabricator via llvm-commits]

sammccall added a comment.

Sorry about the delay, ran into some problems with the tests and decided to simplify them a little by extracting the helper.

Also I think the subdirectory inside $XDG_CACHE_HOME isn't supposed to be hidden, so .clangd->clangd which meant a little refactoring.

Thanks for the patch! Landed as https://github.com/llvm/llvm-project/commit/ad38f4b371bdca214e3a3cda9a76ec2213215c68
