Ensure `build/tmp` exists in `rustdoc_themes::get_themes`
This causes failures in ferrocene's CI as `build/tmp` might not exist at this point, causing the following expect to fail here 4b91288484/src/tools/rustdoc-themes/main.rs (L24)
coverage: Remove debug code from the instrumentor
The coverage instrumentor has an entire module full of complex code that is only used for debugging.
And as I continue to work on coverage, I keep finding that this debug code is constantly causing more trouble than it's worth. It's deeply entangled with current implementation details, such that making any non-trivial change to the instrumentor usually requires major changes to the debug code. And so far I have personally not found any of this debug code to be *useful*.
In light of that situation, I'd like to try just ripping all of it out. If I spend any more time dealing with coverage debug code, I want it to be because I'm writing new and useful tools, not dutifully maintaining a boat-anchor that quite plausibly isn't being used by anyone at all.

clean up unneeded `ToPredicate` impls
Part of #107250.
Removed all totally unused impls. And inlined two impls not need to satisify trait bound.

dependencies: reduce the amount of crates pulling in atty
It would be nice to have only one `hermit-abi` in `Cargo.lock` (https://github.com/rust-lang/rust/pull/107405#issuecomment-1427116590).
The only crate pulling in the old `hermit-abi` version is `atty`, which is unmaintained.
This PR upgrades three dependencies, which then no longer depend on `atty`:
* `Cargo.lock`: `colored v2.0.0 -> v2.0.4`
* `Cargo.lock`: `tracing-tree v0.2.3 -> v0.2.4`
* Miri: `env_logger 0.9.3 -> 0.10.0`
The only dependency chain left that pulls in `hermit-abi 0.1.19` is:
`hermit-abi 0.1.19` -> `atty 0.2.14` -> `env_logger 0.7.1` -> `jsonpath_lib 0.2.6` -> `jsondocck 0.1.0` (src/tools/jsondocck)
Replacing jsondocck with jsondocckng is tracked in https://github.com/rust-lang/rust/issues/94140.
miri: reduce code duplication in some SSE/SSE2 intrinsics
Reduces code duplication in the Miri implementation of some SSE and SSE2 using generics and rustc_const_eval helper functions.
There are also some other minor changes.

Refactor `thread_info` to remove the `RefCell`
`thread_info` currently uses `RefCell`-based initialization. Refactor this to use `OnceCell` instead which is more performant and better suits the needs of one-time initialization.
This is nobody's bottleneck but OnceCell checks are a single `cmp` vs. `RefCell<Option>` needing runtime logic
fix confusing let chain indentation in rustc_resolve
Sorry for opening a PR for such a minor style fix.
This just felt sufficiently misleading to warrant fixing.
Correctly deny late-bound lifetimes from parent in anon consts and TAITs
Reuse the `AnonConstBoundary` scope (introduced in #108553, renamed in this PR to `LateBoundary`) to deny late-bound vars of *all* kinds (ty/const/lifetime) in anon consts and TAITs.
Side-note, but I would like to consolidate this with the error reporting for RPITs (E0657):
c4f25777a0/compiler/rustc_hir_analysis/src/collect/resolve_bound_vars.rs (L733-L754) but the semantics about what we're allowed to capture there are slightly different, so I'm leaving that untouched.
Fixes#115474
Pretty-print argument-position impl trait to name it.
This removes a corner case.
RPIT and TAIT keep having no name, and it would be wrong to use the one in HIR (Ident::empty), so I make this case ICE.
Custom code classes in docs warning
Fixes https://github.com/rust-lang/rust/issues/115938.
This PR does two things:
1. Unless the `custom_code_classes_in_docs` feature is enabled, it will use the old codeblock tag parser.
2. If there is a codeblock tag that starts with a `.`, it will emit a behaviour change warning.
Hopefully this is the last missing part for this feature until stabilization.
Follow-up of https://github.com/rust-lang/rust/pull/110800.

Detect cycle errors hidden by opaques during monomorphization
Opaque types may reveal to projections, which themselves normalize to opaques. We don't currently normalize when checking that opaques are cyclical, and we may also not know that the opaque is cyclical until monomorphization (see `tests/ui/type-alias-impl-trait/mututally-recursive-overflow.rs`).
Detect cycle errors in `normalize_projection_ty` and report a fatal overflow (in the old solver). Luckily, this is already detected as a fatal overflow in the new solver.
Fixes#112047
rustc_target/riscv: Fix passing of transparent unions with only one non-ZST member

move things out of mir/mod.rs
This moves a bunch of things out of `mir/mod.rs`:
- all const-related stuff to a new file consts.rs
- all statement/place/operand-related stuff to a new file statement.rs
- all pretty-printing related stuff to pretty.rs
`mod.rs` started out with 3100 lines and ends up with 1600. :)
Also there was some pretty-printing stuff in terminator.rs, that also got moved to pretty.rs, and I reordered things in pretty.rs so that it can be grouped by functionality.
Only the commit "use pretty_print_const_value from MIR constant 'extra' printing" has any behavior changes; it resolves the issue of having a fancy and a very crude pretty-printer for `ConstValue`.
