[PATCH 2/3] cache.h: move stat_validity definition up

[Jeff King <peff@peff.net>]

It would be nice to embed stat_validity structs inside other
structs defined in cache.h. We cannot get away with a
forward declaration, because using it in a struct definition
means the compiler needs the real size.
