[PATCH] D69327: [Clang][ThinLTO] Add a cache for compile phase output.

[Steven Wu via Phabricator via cfe-commits]

steven_wu added a comment.

`ccache` does not have the support for this, I am just saying that this can be easily implemented in `ccache` and that would be much better than the proposed solution here.

If we need to add a clang driver flag so build system can better support to detect thin bitcode as output and caching them, we should just add the official driver flag.
