Add Tests for native wasm exceptions
### Motivation
In PR #111322, I added support for native WASM exceptions. I was asked by ``@davidtwco`` to add some tests for it in a follow up PR, which seems like a very good idea.
This PR adds three tests for this feature:
* codegen: ensure the correct LLVM instructions are used
* assembly: ensure the correct WASM instructions are used
* run-make: ensure the exception handling works; the WASM code is run using a small nodejs script which demonstrates the exception handling
### Complications
There are a few changes beside adding the tests, which were necessary
* Tests for the wasm32-unknown-unknown target are (as far as I know) only run on `test-various`. Its docker image uses nodejs-15, which is very old. Experimental support for wasm-exceptions was added in nodejs16. In nodejs 18.12 (LTS), they are stable.
- --> increase nodejs to 18.12 in `test-various`
* codegen/assembly tests are not performed for the wasm32-unknown-unknown target yet
- --> add those to `test-various` as well
Due to the last point, some tests are run which have not run before (assembly+codegen tests for wasm32-unknown-unknown). I added `// ignore wasm32-bare` for those which failed
### Local testing
I run all tests locally using both `test-various` and `wasm32`. As far as I know, none of the other systems run any test for wasm32 targets.
Always name the return place.
MIR opts more and more consider `_0` as just another local, so there is no point in keeping the special case in debug-info logic.
Add `needless_pass_by_ref_mut` lint
changelog: [`needless_pass_by_ref_mut`]: This PR add a new lint `needless_pass_by_ref_mut` which emits a warning in case a `&mut` function argument isn't used mutably. It doesn't warn on trait and trait impls functions.
Fixes#8863.
Update debuginfo test runner to provide more useful output
This change makes debuginfo tests more user friendly. Changes:
- Print all lines that fail to match the patterns instead of just the first
- Provide better error messages that also say what did match
- Strip leading whitespace from directives so they are not skipped if indented
- Improve documentation and improve nesting on some related items
As an example, given the following intentional fail (and a few not shown):
```rust
// from tests/debuginfo/rc_arc.rs
// cdb-command:dx rc,d
// cdb-check:rc,d : 111 [Type: alloc::rc::Rc<i32>]
// cdb-check: [Reference count] : 11 [Type: core::cell FAIL::Cell<usize>]
// cdb-check: [Weak reference count] : 2 [Type: core::cell FAIL::Cell<usize>]
```
The current output (tested in #113313) will show:
```

With this chane, you are able to see all failures in that check group, as well as what parts were successful. The output is now:

Which makes it easier to see what did and didn't succeed without manual comparison against the source test file.
Port PGO/LTO/BOLT optimized build pipeline to Rust
This PR ports the `stage-build.py` PGO/LTO/BOLT optimization script from Python to Rust, to make it easier to use dependencies, and make it a bit more robust. The PR switches both the Linux and Windows dist runners to the Rust script and removes the old Python script.
Funnily enough, the Rust port has less lines of code than the Python script :) I think that clearly shows that the Python script really lacked dependencies.
`does_not_fill_wildcard_with_wildcard`
and `does_not_fill_wildcard_with_partial_wildcard_and_wildcard`
both made no modifications to the code,
which is a problem for mutable ast porting as it generates a best-effort
minimal set of text edits,
and assists require at least one text edit.
Don't call `query_normalize` when reporting similar impls
Firstly, It's sketchy to be using `query_normalize` at all during HIR typeck -- it's asking for an ICE 😅. Secondly, we're normalizing an impl trait ref that potentially has parameter types in `ty::ParamEnv::empty()`, which is kinda sketchy as well.
The only UI test change from removing this normalization is that we don't evaluate anonymous constants in impls, which end up giving us really ugly suggestions:
```
error[E0277]: the trait bound `[X; 35]: Default` is not satisfied
--> /home/gh-compiler-errors/test.rs:4:5
|
4 | <[X; 35] as Default>::default();
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ the trait `Default` is not implemented for `[X; 35]`
|
= help: the following other types implement trait `Default`:
&[T]
&mut [T]
[T; 32]
[T; core::::array::{impl#30}::{constant#0}]
[T; core::::array::{impl#31}::{constant#0}]
[T; core::::array::{impl#32}::{constant#0}]
[T; core::::array::{impl#33}::{constant#0}]
[T; core::::array::{impl#34}::{constant#0}]
and 27 others
```
So just fold the impls with a `BottomUpFolder` that calls `ty::Const::eval`. This doesn't work totally correctly with generic-const-exprs, but it's fine for stable code, and this is error reporting after all.

New lint [`manual_partial_ord_and_ord_impl`]
Lints when both `PartialOrd` and `Ord` are manually implemented yet the body of `PartialOrd::partial_cmp` isn't `Some(self.cmp(<other>))`.
This is in `correctness` currently but I'm ok with elsewhere.
Closes#10744

Stop inserting semicolon when extracting match arm
# Overview
Extracting a match arm value that has type unit into a function, when a
comma already follows the match arm value, results in an invalid (syntax
error) semicolon added between the newly generated function's generated
call and the comma.
# Example
Running this extraction
```rust
fn main() {
match () {
_ => $0()$0,
};
}
```
would lead to
```rust
fn main() {
match () {
_ => fun_name();,
};
}
fn fun_name() {
}
```
# Issue / Fix details
This happens because when there is no comma, rust-analyzer would simply
add the comma and wouldn't even try to evaluate whether it needs to add
a semicolon. But when the comma is there, it proceeds to evaluate
whether it needs to add a semicolon and it looks like the evaluation
logic erroneously ignores the possibility that we're in a match arm.
IIUC it never makes sense to add a semicolon when we're extracting from
a match arm value, so I've adjusted the logic to always decide against
adding a semicolon when we're in a match arm
