Yes, the ccache cache is persisted across runs (see the *_cache and
upload_cache inststructions). It makes a quite substantial difference. One
reason the windows runs are a lot slower than the others is just that visual
studio isn't yet supported by ccache, and that there doesn't seem to be good
other tools.

The ccache maintainers merged more of the msvc support last weekend! So I have
quite a bit of hope of being able to use ccache there as well.
