This causes the build to take just over an hour, so probably not worth it...

The 16 core runner is 2x the cost of a 8 core runner, so if the build time isn't <=1/2 with 16 cores this is worth it. Just over an hour to me sounds like we're probably in the worth it range?

@Mark-Simulacrum Hmm ok, well we should consider it alongside #119399 which finds more bugs but also increases the build time to 50m. Combining the two would probably make it too slow...

I guess we should find out :)

@Mark-Simulacrum How would you feel about 1h 21m if we also merged #119399 (which is 50m on 16 cores)? Judging by recent builds, it looks like it's still over 30m away from being the long pole...

I have no objections to anything significantly (10m?) shorter than long pole.

Bump Fuchsia, build tests, and use 8 core bots

- Build Fuchsia on 8 cores instead of 16
- Skip building cranelift for Fuchsia
- Bump Fuchsia (includes building tests)

This includes a change to the upstream build_fuchsia_from_rust_ci script that builds a minimal set of tests, to improve coverage on this builder.

See prior discussion on rust-lang#119400 about building on 8 cores instead of 16. This PR combines changes from that and rust-lang#119399, plus clean up.
