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. This would have caught https://github.com/rust-lang/rust-clippy/issues/11952 and #119593.
See prior discussion on #119400 about building on 8 cores instead of 16. This PR combines changes from that and #119399, plus clean up.
r? `@Mark-Simulacrum`
in particular, this makes the `c` feature for compiler-builtins an explicit opt-in, rather than silently detected by whether `llvm-project` is checked out on disk.
exposing this is necessary because the `cc` crate doesn't support cross-compiling to MSVC, and we want people to be able to run `x check --target foo` regardless of whether they have a c toolchain available.
this also uses the new option in CI, where we *do* want to optimize compiler_builtins.
the new option is off by default for the `dev` channel and on otherwise.
The compiler-builtins for RISC-V are missing some key functions, such as
__bswapsi2 [1].
We can't just pull in the LLVM compiler-rt builtins as the rust-lang/rust
distribution container doesn't have a C compiler [2].
This patch adds RISC-V C compilers to the CI Dockerfile as the first
step towards enabling LLVM compiler-rt builtins for RISC-V Rust.

Let `reuse` look inside git submodules
Changes `collect-license-metadata` and `generate-copyright` so they can now look at the git submodules.
Unfortunately `reuse` chokes on the LLVM submodule - it finds the word "Copyright" or the unicode copyright symbol in all kinds of places, including UTF-8 test cases. The `reuse` tool expressly won't let you ignore folders, so we let it scan everything and then strip out the LLVM sub-folder in post. Instead, we add in a hand-curated list of copyright information gleaned by reading the LLVM codebase carefully, which is stored in `.reuse/dep5` in Debian format where `reuse` can find and use it.
The `.reuse/dep5` continues to track copyright info for files in the tree that do not have SPDX metadata in them (i.e. all of them)
Re-enable `rustc_codegen_gcc` tests in CI
When #117947 dropped llvm-15 from CI, we neglected to copy #117313's changes to enable `rustc_codegen_gcc` testing to the new base llvm-16. This is now restored, as well as copying the setup to llvm-17 as well so we hopefully won't miss it next time.
In addition, due to case mismatch in `$extra_env` updates in `docker/run.sh`, I think it wasn't actually getting enabled before, but this should now be fixed. I also avoided the linker hack for `libgccjit.so` that was present before, because that's not needed if the version matches the base `gcc` used for linking.

Remove asmjs
Fulfills [MCP 668](https://github.com/rust-lang/compiler-team/issues/668).
`asmjs-unknown-emscripten` does not work as-specified, and lacks essential upstream support for generating asm.js, so it should not exist at all.
The subcommand `ffx product-bundle` has been removed, and replaced with
the subcommand `ffx product`. This changes `fuchsia-test-runner.py` to
use it to download the SDK and product bundle for the latest release of
Fuchsia.
Run tidy license checker on more workspaces
The license checker didn't run on several workspaces before this PR. The same applied to the "external package sources" check. There were also two missing lockfiles which I have added now.
This reverts commit 1dfb6b162be402d8ca37e8aad4f58898b44e3a15, reversing
changes made to bcb5798dd890a691644af9d371f3bd7fcc465584.
That commit broke generating nightly rustc docs. Revert it until we can figure out how to have both, cranelift and docs.
