Move `TyCtxt::mk_x` to `Ty::new_x` where applicable
Part of rust-lang/compiler-team#616
turns out there's a lot of places we construct `Ty` this is a ridiculously huge PR :S

style-guide: Clarify grammar for small patterns (not a semantic change)
The grammar as written feels ambiguous and confusing, in large part
because it uses square brackets and commas in the names of
non-terminals. Rewrite it to avoid symbols in the names of
non-terminals, and to instead wrap terminals in backquotes.
Also rename "smallntp" to "small_no_tuple" to make it self-describing.
Fix submodule handling when the current branch is named after a tag
If:
1. The current branch has the same name as git tag, and
2. The current branch is set to track a remote other than `origin`, and
3. We try to update a submodule
then we'll get the following error:
```
; x c
Updating submodule src/doc/reference
remote: Total 0 (delta 0), reused 0 (delta 0), pack-reused 0
fatal: 'personal' does not appear to be a git repository
fatal: Could not read from remote repository.
```
The problem is that 1. causes `git symbolic-ref --short HEAD` to try and disambiguate the branch from the tag using `heads/branch-name`, which breaks a previous workaround for a bug in `git submodule update` that uses the wrong remote.
Adapt the workaround to strip `heads/` from the output.
Revert the lexing of `c"…"` string literals
Fixes \[after beta-backport\] #113235.
Further progress is tracked in #113333.
This PR *manually* reverts parts of #108801 (since a git-revert would've been too coarse-grained & messy)
and git-reverts #111647.

style-guide: Document newline rules for assignment operators
The style guide gives general rules for binary operators including
assignment, and one of those rules says to put the operator on the
subsequent line; the style guide needs to explicitly state the exception
of breaking *after* assignment operators rather than before.
This is already what rustfmt does and what users do; this fixes the
style guide to match the expected default style.
Specialize `try_destructure_mir_constant` for its sole user (pretty printing)
We can't remove the query, as we need to invoke it from rustc_middle, but can only implement it in mir interpretation/const eval.
r? `@RalfJung` for a first round.
While we could move all the logic into pretty printing, that would end up duplicating a bit of code with const eval, which doesn't seem great either.

enable test_join test in Miri
Miri for quite a while now has a hack to support self-referential generators: non-`Unique` mutable references are exempt from aliasing conditions. So we can run this test now. (It passes.)
Also extend a comment in a Vec test, while I am at it.

Move most coverage code out of `rustc_codegen_ssa`
*This is one step in my larger coverage refactoring ambitions described at <https://github.com/rust-lang/compiler-team/issues/645>.*
The backend implementation of coverage instrumentation was originally split between SSA and LLVM, perhaps in the hopes that it could be used by other backends.
In practice, this split mostly just makes the coverage implementation harder to navigate and harder to modify. It seems unlikely that any backend will actually implement coverage instrumentation in the foreseeable future, especially since many parts of the existing implementation (outside the LLVM backend) are heavily tied to the specific details of LLVM's coverage instrumentation features.
The current shared implementation of `codegen_coverage` is heavily tied to the details of `StatementKind::Coverage`, which makes those details difficult to change. I have reason to want to change those details as part of future fixes/improvements, so this will reduce the amount of interface churn caused by those later changes.
---
This is intended to be a pure refactoring change, with no changes to actual behaviour. All of the “added” code has really just been moved from other files.
Winnow specialized impls during selection in new solver
We need to be able to winnow impls that are specialized by more specific impls in order for codegen to be able to proceed.
r? ``@lcnr``
Move `ty::ConstKind` to `rustc_type_ir`
Needed this in another PR for custom debug impls, and this will also be required to move the new solver into a separate crate that does not use `TyCtxt` so that r-a and friends can depend on the trait solver.
Rebased on top of #113325, only the second and third commits needs reviewing
Add some extra information to opaque type cycle errors
Plus a bunch of cleanups.
This should help users debug query cycles due to auto trait checking. We'll probably want to fix cycle errors in most (or all?) cases by looking at the current item's hidden types (new solver does this), and by delaying the auto trait checks to after typeck.
