Remove queries from the driver interface
All uses of driver queries in the public api of rustc_driver have been removed in https://github.com/rust-lang/rust/pull/134130 already. This removes driver queries from rustc_interface and does a couple of cleanups around TyCtxt construction and entering enabled by this removal.
Finishes the removal of driver queries started with https://github.com/rust-lang/rust/pull/126834.

Some trait method vs impl method signature difference diagnostic cleanups
Just some things I noticed while debugging a weird diagnostic in https://github.com/rust-lang/rust/pull/134353
best reviewed commit by commit
Check for array lengths that aren't actually `usize`
I wish typeck wouldn't give us `ty::Array`s that have this problem in the first place, but we can check for it.
Fixes#134352

reject unsound toggling of RISCV target features
~~Stacked on top of https://github.com/rust-lang/rust/pull/133417, only the last commit is new.~~
Works towards https://github.com/rust-lang/rust/issues/132618 (but more [remains to be done](https://github.com/rust-lang/rust/pull/134337#issuecomment-2544228958))
Part of https://github.com/rust-lang/rust/issues/116344
Cc ``@beetrees`` I hope I got everything. I didn't do anything about "The f and zfinx features are incompatible" and that's not an ABI thing (right?) and I am not sure how to handle it with these ABI checks.
r? ``@workingjubilee``
Ideally we'd also reject target specs that disable the `f` feature but set an ABI that requires `f`... but I don't want to duplicate this logic. I have some ideas for how maybe the entire float ABI check logic should be different, now that we have some examples of what these ABI checks look like, but that will be a future PR.
Keep track of patterns that could have introduced a binding, but didn't
When we recover from a pattern parse error, or a pattern uses `..`, we keep track of that and affect resolution error for missing bindings that could have been provided by that pattern. We differentiate between `..` and parse recovery. We silence resolution errors likely caused by the pattern parse error.

rustdoc-search: handle `impl Into<X>` better
This PR fixes two bugs I ran into while searching the compiler docs:
- It omitted an `impl Trait` entry in the type signature field, producing `TyCtxt, , Symbol -> bool`
- It didn't let me search for `TyCtxt, DefId, Symbol -> bool` even though that's a perfectly good description of the function I was looking for (the function actually used `impl Into<DefId>`

Correctly handle comments in attributes in doctests source code
Fixes https://github.com/rust-lang/rust/issues/134221.
The problem was that attributes are "inlined" (backlines are stripped), then when there is an inline comment inside it, the attribute is never considered valid (since unclosed). Fix was to simply put back backlines in case it's a multiline attribute.

rustc_mir_build: Clarify that 'mirrored' does not mean 'flipped' or 'reversed'
My intuition for 'mirrored' is that it means 'flipped' or 'reversed'. Clarify that that is not what is meant to 'mirror' the THIR from the HIR.

Update spelling of "referring"
I noticed that `referring` was spelled incorrectly in the output of `unexpected 'cfg' condition name` warnings; it looks like it was also incorrectly spelled in a doc comment. I've update both instances.
Fix `trimmed_def_paths` ICE in the function ptr comparison lint
This PR fixes an ICE with `trimmed_def_paths` ICE in the function ptr comparison lint, specifically when pretty-printing user types but then not using the resulting pretty-printing.
Fixes#134345

Make sure to use normalized ty for unevaluated const in default struct value
This cleans up the way that we construct the `mir::Const::Unevaluated` for default struct values. We were previously using `from_unevaluated`, which doesn't normalize the type, and is really only used for inline assembly. Other codepaths (such as `ExprKind::NamedConst`) use the type from the body.
Also, let's stop using `literal_operand`, which also is really not meant for calls other than for literal comparisons in pattern lowering.
Also move all of the tests to a separate subdirectory so they don't need to have the same prefix on all the test files.
Fixes#134298

Hir attributes
This PR needs some explanation, it's somewhat large.
- This is step one as described in https://github.com/rust-lang/compiler-team/issues/796. I've added a new `hir::Attribute` which is a lowered version of `ast::Attribute`. Right now, this has few concrete effects, however every place that after this PR parses a `hir::Attribute` should later get a pre-parsed attribute as described in https://github.com/rust-lang/compiler-team/issues/796 and transitively https://github.com/rust-lang/rust/issues/131229.
- an extension trait `AttributeExt` is added, which is implemented for both `ast::Attribute` and `hir::Atribute`. This makes `hir::Attributes` mostly compatible with code that used to parse `ast::Attribute`. All its methods are also added as inherent methods to avoid having to import the trait everywhere in the compiler.
- Incremental can not not hash `ast::Attribute` at all.
Pass `TyCtxt` to early diagostics decoration
This PR pass a `TyCtxt` to the early diagnostics decoration code so that diagnostics code that take advantage of (a very limited but still useful) `TyCtxt` in their note, help, suggestions, ...
This is particulary useful for #133221 which wants to get the crate name of a `DefId`, which is possible with `tcx.crate_name(...)`.
I highly recommend reviewing this PR commit by commit.

bootstrap: make ./x test error-index work
This makes it more likely that someone who sees an error index CI failure will be able to figure out how to reproduce that locally. Note that bootstrap already prints "Testing stage2 error-index", which is misleading since the test is actually called error_index_generator.
Fix `--nocapture` for run-make tests
This was confusing because there are three layers of output hiding.
1. libtest shoves all output into a buffer and does not print it unless the test fails or `--nocapture` is passed.
2. compiletest chooses whether to print the output from any given process.
3. run-make-support chooses what output to print.
This modifies 2 and 3.
- compiletest: Don't require both `--verbose` and `--nocapture` to show the output of run-make tests.
- compiletest: Print the output from `rmake` processes if they succeed. Previously this was only printed on failure.
- compiletest: Distinguish rustc and rmake stderr by printing the command name (e.g. "--stderr--" to "--rustc stderr--").
- run-make-support: Unconditionally print the needle/haystack being searched. Previously this was only printed on failure.
