Either generate it with the actual codegen backend dylib or omit it
entirely when the cranelift backend is disabled for this build.

consts: remove dead code around `i1` constant values
`LLVMConstZext` recently got deleted, and it turns out (thanks to `@nikic` for knowing!) that this is dead code. Tests all pass for me without this logic, and per nikic:
> We always generate constants in "relocatable bag of bytes"
> representation, so you're never going to get a plain bool.
So this should be a safe thing to do.

Use `filter_map` in `try_par_for_each_in`
This simplifies the expression, especially for the rayon part, and also
lets us drop the `E: Copy` constraint.

Cleanup `rustc_mir_build/../check_match.rs`
The file had become pretty unwieldy, with a fair amount of duplication. As a bonus, I discovered that we weren't running some pattern checks in if-let chains.
I recommend looking commit-by-commit. The last commit is a whim, I think it makes more sense that way but I don't hold this opinion strongly.

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.

Remove support for compiler plugins.
They've been deprecated for four years.
This commit includes the following changes.
- It eliminates the `rustc_plugin_impl` crate.
- It changes the language used for lints in `compiler/rustc_driver_impl/src/lib.rs` and `compiler/rustc_lint/src/context.rs`. External lints are now called "loaded" lints, rather than "plugins" to avoid confusion with the old plugins. This only has a tiny effect on the output of `-W help`.
- E0457 and E0498 are no longer used.
- E0463 is narrowed, now only relating to unfound crates, not plugins.
- The `plugin` feature was moved from "active" to "removed".
- It removes the entire plugins chapter from the unstable book.
- It removes quite a few tests, mostly all of those in `tests/ui-fulldeps/plugin/`.
Closes #29597.

Guarantee representation of None in NPO
This allows users to soundly transmute zeroes into `Option` types subject to the null pointer optimization (NPO). It unblocks https://github.com/google/zerocopy/issues/293.

Revert "Auto merge of #117328 - lqd:cranelift-rocket, r=Mark-Simulacrum"
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.
Fixes https://github.com/rust-lang/rust/issues/117430

Add track_caller to transmute_copy
Currently if `size_of::<Src>() < size_of::<Dst>()` you will see the following error:
```rust
thread 'test' panicked at /rustc/cc66ad468955717ab92600c770da8c1601a4ff33/library/core/src/mem/mod.rs:1056:5:
cannot transmute_copy if Dst is larger than Src
```
This fixes it so it will show the invocation location

Add all RPITITs when augmenting param-env with GAT bounds in `check_type_bounds`
When checking that associated type definitions actually satisfy their associated type bounds in `check_type_bounds`, we construct a "`normalize_param_env`" which adds a projection predicate that allows us to assume that we can project the GAT to the definition we're checking. For example, in:
```rust
type Foo {
type Bar: Display = i32;
}
```
We would add `<Self as Foo>::Bar = i32` as a projection predicate when checking that `i32: Display` holds.
That `normalize_param_env` was, for some reason, only being used to normalize the predicate before it was registered. This is sketchy, because a nested obligation may require the GAT bound to hold, and also the projection cache is broken and doesn't differentiate projection cache keys that differ by param-envs 😿.
This `normalize_param_env` is also not sufficient when we have nested RPITITs and default trait methods, since we need to be able to assume we can normalize both the RPITIT and all of its child RPITITs to sufficiently prove all of its bounds. This is the cause of #117104, which only starts to fail for RPITITs that are nested 3 and above due to the projection-cache bug above.[^1]
## First fix
Use the `normalize_param_env` everywhere in `check_type_bounds`. This is reflected in a test I've constructed that fixes a GAT-only failure.
## Second fix
For RPITITs, install projection predicates for each RPITIT in the same function in `check_type_bounds`. This fixes #117104.
not sure who to request, so...
r? `@lcnr` hehe feel free to reassign :3
[^1]: The projection cache bug specifically occurs because we try normalizing the `assumed_wf_types` with the non-normalization param-env. This causes us to insert a projection cache entry that keeps the outermost RPITIT rigid, and it trivially satisifes all its own bounds. Super sketchy![^2]
[^2]: I haven't actually gone and fixed the projection cache bug because it's only marginally related, but I could, and it should no longer be triggered here.

dropck_outlives check whether generator witness needs_drop
see https://rust-lang.zulipchat.com/#narrow/stream/326866-t-types.2Fnominated/topic/.23116242.3A.20Code.20no.20longer.20compiles.20after.20-Zdrop-tracking-mir.20.E2.80.A6/near/398311627 for an explanation.
Fixes #116242 (or well, the repro by `@jamuraa` in https://github.com/rust-lang/rust/issues/116242#issuecomment-1739802047). I did not add a regression test as it depends on other crates. We do have 1 test going from fail to pass, showing the intended behavior.

It makes the code a little nicer.
As part of this, the interner's `Default` impl is removed and `prefill`
is used in a test instead.
