This makes it easier to open the messages file while developing on features.
The commit was the result of automatted changes:

Make `rustc_query_system` take `QueryConfig` by instance.
This allows for easy switching between virtual tables and specialized instances for queries. It also has the benefit of less turbofish. `QueryStorage` has also been merged with `QueryCache`.

errors: generate typed identifiers in each crate
Instead of loading the Fluent resources for every crate in `rustc_error_messages`, each crate generates typed identifiers for its own diagnostics and creates a static which are pulled together in the `rustc_driver` crate and provided to the diagnostic emitter.
There are advantages and disadvantages to this change..
#### Advantages
- Changing a diagnostic now only recompiles the crate for that diagnostic and those crates that depend on it, rather than `rustc_error_messages` and all crates thereafter.
- This approach can be used to support first-party crates that want to supply translatable diagnostics (e.g. `rust-lang/thorin` in https://github.com/rust-lang/rust/pull/102612#discussion_r985372582, cc `@JhonnyBillM)`
- We can extend this a little so that tools built using rustc internals (like clippy or rustdoc) can add their own diagnostic resources (much more easily than those resources needing to be available to `rustc_error_messages`)
#### Disadvantages
- Crates can only refer to the diagnostic messages defined in the current crate (or those from dependencies), rather than all diagnostic messages.
- `rustc_driver` (or some other crate we create for this purpose) has to directly depend on *everything* that has error messages.
- It already transitively depended on all these crates.
#### Pending work
- [x] I don't know how to make `rustc_codegen_gcc`'s translated diagnostics work with this approach - because `rustc_driver` can't depend on that crate and so can't get its resources to provide to the diagnostic emission. I don't really know how the alternative codegen backends are actually wired up to the compiler at all.
- [x] Update `triagebot.toml` to track the moved FTL files.

Use a lock-free datastructure for source_span
follow up to the perf regression in https://github.com/rust-lang/rust/pull/105462
The main regression is likely the CStore, but let's evaluate the perf impact of this on its own
Don't call `with_reveal_all_normalized` in const-eval when `param_env` has inference vars in it
**what:** This slightly shifts the order of operations from an existing hack:
5b6ed253c4/compiler/rustc_middle/src/ty/consts/kind.rs (L225-L230)
in order to avoid calling a tcx query (`TyCtxt::reveal_opaque_types_in_bounds`, via `ParamEnv::with_reveal_all_normalized`) when a param-env has inference variables in it.
**why:** This allows us to enable fingerprinting of query keys/values outside of incr-comp in deubg mode, to make sure we catch other places where we're passing infer vars and other bad things into query keys. Currently that (bbf33836b9) crashes because we introduce inference vars into a param-env in the blanket-impl finder in rustdoc 😓5b6ed253c4/src/librustdoc/clean/blanket_impl.rs (L43)
See the CI failure here: https://github.com/rust-lang/rust/actions/runs/4058194838/jobs/6984834619
Factor query arena allocation out from query caches
This moves the logic for arena allocation out from the query caches into conditional code in the query system. The specialized arena caches are removed. A new `QuerySystem` type is added in `rustc_middle` which contains the arenas, providers and query caches.
Performance seems to be slightly regressed:

Incremental performance is a bit worse:

It does seem like LLVM optimizers struggle a bit with the current state of the query system.

Convert all the crates that have had their diagnostic migration
completed (except save_analysis because that will be deleted soon and
apfloat because of the licensing problem).
Abolish `QueryVTable` in favour of more assoc items on `QueryConfig`
This may introduce additional mono _but_ may help const fold things better and especially may help not constructing a `QueryVTable` anymore which is cheap but not free.

Remove the `..` from the body, only a few invocations used it and it's
inconsistent with rust syntax.
Use `;` instead of `,` between consts. As the Rust syntax gods inteded.
This makes sure that ICEing because of def ids created outside of ast lowering will be able to produce a query backtrace and not cause a double panic because of trying to call the `def_span` query
make `error_reported` check for delayed bugs
Fixes#104768
`error_reported()` was only checking if there were errors emitted, not for `delay_bug`s which can also be a source of `ErrorGuaranteed`. I assume the same is true of `lint_err_count` but i dont know
`AddToDiagnostic::add_to_diagnostic_with` is similar to the previous
`AddToDiagnostic::add_to_diagnostic` but takes a function that can be
used by the caller to modify diagnostic messages originating from the
subdiagnostic (such as performing translation eagerly).
`add_to_diagnostic` now just calls `add_to_diagnostic_with` with an
empty closure.
