Specifically this should improve linking by producing one large binary instead of one-per-directory. The inclusion of the driver hits the size issue. Separating out things which have more llvm deps has been discussed, but I'm not doing that here because I think the semantics layer will need to depend on clang for interop, and we'd lose a lot of the benefits that way. Also, having just one place to look seems simpler. Includes supporting changes to file_test infrastructure, the most significant of which is probably passing tests via file instead of a really large args thing, using a custom rule to do that. That's because dealing with the layered filegroups that allow the toolchain setup is more complicated, and this approach scales well. Combined test time is ~9s, so not sharding right now. I wasn't sure if people would prefer having the autoupdate script under testing, so I left it alone for now.
