abi: add AddressSpace field to Primitive::Pointer
...and remove it from `PointeeInfo`, which isn't meant for this.
There are still various places (marked with FIXMEs) that assume all pointers
have the same size and alignment. Fixing this requires parsing non-default
address spaces in the data layout string (and various other changes),
which will be done in a followup.
(That is, if it's actually worth it to support multiple different pointer sizes.
There is a lot of code that would be affected by that.)

Fix escaping inference var ICE in `point_at_expr_source_of_inferred_type`
Fixes#107158
`point_at_expr_source_of_inferred_type` uses `lookup_probe` to adjust the self type of a method receiver -- but that method returns inference variables from inside a probe. That means that the ty vars are no longer valid, so we can't use any infcx methods on them.
Also, pass some extra span info to hack a quick solution to bad labels, resulting in this diagnostic improvement:
```rust
fn example2() {
let mut x = vec![1];
x.push("");
}
```
```diff
error[E0308]: mismatched types
--> src/main.rs:5:12
|
5 | x.push("");
| ---- ^^
| | |
| | expected integer, found `&str`
- | | this is of type `&'static str`, which causes `x` to be inferred as `Vec<{integer}>`
| arguments to this method are incorrect
```
(since that "which causes `x` to be inferred as `Vec<{integer}>` part is wrong)

Delete `SimplifyArmIdentity` and `SimplifyBranchSame` mir opts
I had attempted to fix the first of these opts in #94177 . However, despite that PR already being a full re-write, it still did not fix some of the core soundness issues. The optimizations that are attempted here are likely to be desirable, but I do not expect any of the currently written code to survive into a sound implementation. Deleting the code keeps us from having to maintain the passes in the meantime.

rustdoc: rearrange HTML in primitive reference links
This patch avoids hard-to-click single character links by making the generic part of the link:
Before: <a href="#">&</a>T
After: <a href="#">&T</a>
Suggest using a lock for `*Cell: Sync` bounds
I mostly did this for `OnceCell<T>` at first because users will be confused to see that the `OnceCell<T>` in `std` isn't `Sync` but then extended it to `Cell<T>` and `RefCell<T>` as well.
Add hint for missing lifetime bound on trait object when type alias is used
Fix issue #103582.
The problem: When a type alias is used to specify the return type of the method in a trait impl, the suggestion for fixing the problem of "missing lifetime bound on trait object" of the trait impl will not be created. The issue caused by the code which searches for the return trait objects when constructing the hint suggestion is not able to find the trait objects since they are specified in the type alias path instead of the return path of the trait impl.
The solution: Trace the trait objects in the type alias path and provide them along with the alias span to generate the suggestion in case the type alias is used in return type of the method in the trait impl.
use `LocalDefId` instead of `HirId` in trait resolution to simplify the obligation clause resolution
This commit introduces a refactoring suggested by `@lcnr` to simplify the obligation clause resolution.
This is just the first PR that introduces a type of refactoring, but others PRs will follow this to introduce name changing to change from the variable name from `body_id` to something else.

rustdoc: simplify settings popover DOM, CSS, JS
* Change the class names so that they all start with `setting-`. That should make it harder to accidentally use a setting class outside the settings popover, where loading the CSS might accidentally change the styles of something unrelated.
* Get rid of an unnecessary wrapper DIV around the radio button line.
* Simplify CSS selectors by making the DOM easier and more intuitive to target.
* Remove dead settings JS for obsolete select-wrapper
`sub_ptr()` is equivalent to `usize::try_from().unwrap_unchecked()`, not `usize::from().unwrap_unchecked()`
`usize::from()` gives a `usize`, not `Result<usize>`, and `usize: From<isize>` is not implemented.
Add suggestion to remove if in let..else block
Adds an additional hint to failures where we encounter an else keyword while we're parsing an if-let expression.
This is likely that the user has accidentally mixed if-let and let..else together.
Fixes#103791.
rustc_metadata: Support non-`Option` nullable values in metadata tables
This is a convenience feature for cases in which "no value in the table" and "default value in the table" are equivalent.
Tables using `Table<DefIndex, ()>` are migrated in this PR, some other cases can be migrated later.
This helps `DocFlags` in https://github.com/rust-lang/rust/pull/107136 in particular.
Allow fmt::Arguments::as_str() to return more Some(_).
This adjusts the documentation to allow optimization of format_args!() to be visible through fmt::Arguments::as_str().
This allows for future changes like https://github.com/rust-lang/rust/pull/106824.
Allow setting CFG_DISABLE_UNSTABLE_FEATURES to 0
Two locations check whether this build-time environment variable is defined. Allowing it to be explicitly disabled with a "0" value is useful, especially for integrating with external build systems.
