Categorize queries for later self-profiling
Change the define_queries! macro per feedback on #51657.
Big thanks to @mark-i-m for the help getting the macro changes correct!
I'm pulling this commit out of the other PR because it's hard to keep up-to-date as queries are added or changed.

Squash all lints tied to foreign macros by default
This PR is a continuation of https://github.com/rust-lang/rust/pull/49755 (thanks for the initial jump-start @Dylan-DPC!) and is targeted at solving https://github.com/rust-lang/rust/issues/48855. This change updates the lint infrastructure to, by default, ignore all lints emitted for code that originates in a foreign macro. For example if `println!("...")` injects some idiomatic warnings these are all ignored by default. The rationale here is that for almost all lints there's no action that can be taken if the code originates from a foreign lint.

rustc: Stabilize #[wasm_import_module] as #[link(...)]
This commit stabilizes the `#[wasm_import_module]` attribute as
`#[link(wasm_import_module = "...")]`. Tracked by #52090 this new directive in
the `#[link]` attribute is used to configured the module name that the imports
are listed with. The WebAssembly specification indicates two utf-8 names are
associated with all imported items, one for the module the item comes from and
one for the item itself. The item itself is configurable in Rust via its
identifier or `#[link_name = "..."]`, but the module name was previously not
configurable and defaulted to `"env"`. This commit ensures that this is also
configurable.
Closes#52090
When encountering format string errors in a raw string, or regular
string literal with embedded newlines, account for the positional
change to use correct spans.
:drive by fix: 🚗
- Don't print the newline on its own to avoid the possibility of
printing it out of order due to `stdout` locking.
- Modify wording of `concat!()` with non-literals to not mislead into
believing that only `&str` literals are accepted.
- Add test for `concat!()` with non-literals.
Using a `BTreeMap` to represent rows in the bit matrix is really slow.
This patch changes things so that each row is represented by a
`BitVector`. This is a less sparse representation, but a much faster
one.
As a result, `SparseBitSet` and `SparseChunk` can be removed.
Other minor changes in this patch.
- It renames `BitVector::insert()` as `merge()`, which matches the
terminology in the other classes in bitvec.rs.
- It removes `SparseBitMatrix::is_subset()`, which is unused.
- It reinstates `RegionValueElements::num_elements()`, which #52190 had
removed.
- It removes a low-value `debug!` call in `SparseBitMatrix::add()`.
sync::Once use release-acquire access modes
Nothing here makes a case distinction like "this happened before OR after that". All we need is to get happens-before edges whenever we see that the state/signal has been changed. Release-acquire is good enough for that.
RFC 2008 non-exhaustive enums/structs: Rustdoc
Part of #44109. Not sure how those who maintain rustdoc primarily would prefer this addition look or where it should be placed, happy to make any changes required.
r? @QuietMisdreavus (not sure if this is the right person, just guessing)
We used to hardcode that we wanted the liveness of *all* variables.
This can now be configured by selecting an alternative index type
V and providing a (partial) map from locals to that new type V.
