As of rust-lang#133155 `Formatter:new` uses `as_results_cursor` to create a non-mutable results reference, and then later that is accessed via `deref_mut` which results in a runtime abort. Changing to `as_results_cursor_mut` fixes it. Fixes rust-lang#133641.
The `Borrowed` variant is no longer used. This commit removes it, along with the `as_results_cursor` method that produces it, and renames `as_results_cursor_mut` as `as_results_cursor`.

Mark the following API const stable:
impl<T> MaybeUninit<T> {
pub const fn write(&mut self, val: T) -> &mut T;
}
This depends on `const_mut_refs` and `const_maybe_uninit_assume_init`,
both of which have recently been stabilized.
Tracking issue: <rust-lang#63567>
These operations are much more about lowering the HIR than about `Const`s themselves. They fit better in hir_ty_lowering with `lower_const_arg` (formerly `Const::from_const_arg`) and the rest. To accomplish this, `const_evaluatable_predicates_of` had to be changed to not use `from_anon_const` anymore. Instead of visiting the HIR and lowering anon consts on the fly, it now visits the `rustc_middle::ty` data structures instead and directly looks for `UnevaluatedConst`s. This approach was proposed in: rust-lang#131081 (comment)

Stabilize `const_maybe_uninit_write`
Mark the following API const stable:
```rust
impl<T> MaybeUninit<T> {
pub const fn write(&mut self, val: T) -> &mut T;
}
```
This depends on `const_mut_refs` and [`const_maybe_uninit_assume_init`](rust-lang#86722), both of which have recently been stabilized.

…ure-compat, r=davidtwco show forbidden_lint_groups in future-compat reports Part of rust-lang#81670. This has been a future-compat lint for a while, time to dial it up to show up in reports.

Move `Const::{from_anon_const,try_from_lit}` to hir_ty_lowering
Fixes rust-lang#128176.
This accomplishes one of the followup items from rust-lang#131081.

Use c"lit" for CStrings without unwrap
I've reviewed uses of `CString::new("lit")`.
Some could be changed to `c"lit"`. Some could be changed to `c"lit".to_owned()`, avoiding an `unwrap()`.
Many `CString` documentation examples could be simplified. I deliberately haven't changed all the examples to use the exact same expression, so that they can demonstrate many ways of creating `CString`s.
I've left UI tests mostly unchanged, because `c""` requires edition 2021, but most UI tests use 2015, and I didn't want to accidentally change what the tests are testing.
…e, r=compiler-errors fix ICE when promoted has layout size overflow Turns out there is no reason to distinguish `tainted_by_errors` and `can_be_spurious` here, we can just track whether we allow this even in "infallible" constants. Fixes rust-lang#125476
add "profiler" and "optimized-compiler-builtins" option coverage for ci-rustc Adds "profiler" and "optimized-compiler-builtins" option coverage in CI-rustc config compatibility check. Resolves rust-lang#133675
…cs, r=jieyouxu Reducing `target_feature` check-cfg merge conflicts It was rightfully pointed in rust-lang#133099 (comment) that the expected values for the `target_feature` cfg are regularly updated and unfortunately the check-cfg tests for it are very merge-conflict prone. This PR aims at drastically reducing the likely-hood of those, by normalizing the "and X more" diagnostic, as well as making the full expected list multi-line instead of being on a single one. cc `@RalfJung` r? `@jieyouxu`

Change `AttrArgs::Eq` to a struct variant Cleanups for simplifying rust-lang#131808 Basically changes `AttrArgs::Eq` to a struct variant and then avoids several matches on `AttrArgsEq` in favor of methods on it. This will make future refactorings simpler, as they can either keep methods or switch to field accesses without having to restructure code
