This makes it clearer that it is set by the build system rather than by
the rustc that compiles the current rustc. It also avoids bootstrap
needing to pass --check-cfg llvm_enzyme to rustc.
This was done in #145740 and #145947. It is causing problems for people
using r-a on anything that uses the rustc-dev rustup package, e.g. Miri,
clippy.
This repository has lots of submodules and subtrees and various
different projects are carved out of pieces of it. It seems like
`[workspace.dependencies]` will just be more trouble than it's worth.
With the new resolver, a few dependencies get brought in twice with
different licenses. For example, all dependencies from `wasm-tools`
gained Apache-2.0 and MIT options, and with the v2 resolver we were
using one version from before and one version from after this change.
This made tidy's license check difficult.
Update some minimum versions to remove duplicate dependencies and smooth
out license checking.
Create the rustc_sanitizers crate and move the source code for the CFI
and KCFI sanitizers to it.

This involves lots of breaking changes. There are two big changes that
force changes. The first is that the bitflag types now don't
automatically implement normal derive traits, so we need to derive them
manually.
Additionally, bitflags now have a hidden inner type by default, which
breaks our custom derives. The bitflags docs recommend using the impl
form in these cases, which I did.
- Sort dependencies and features sections.
- Add `tidy` markers to the sorted sections so they stay sorted.
- Remove empty `[lib`] sections.
- Remove "See more keys..." comments.
Excluded files:
- rustc_codegen_{cranelift,gcc}, because they're external.
- rustc_lexer, because it has external use.
- stable_mir, because it has external use.
Fluent, with all the icu4x it brings in, takes quite some time to
compile. `fluent_messages!` is only needed in further downstream rustc
crates, but is blocking more upstream crates like `rustc_index`. By
splitting it out, we allow `rustc_macros` to be compiled earlier, which
speeds up `x check compiler` by about 5 seconds (and even more after the
needless dependency on `serde_json` is removed from
`rustc_data_structures`).
This was broken because the synthetic object files produced by rustc
were for 64-bit AArch64, which caused link failures when combined with
32-bit ILP32 object files.
This PR updates the object crate to 0.30.1 which adds support for
generating ILP32 AArch64 object files.
