rust-installer: Use env(1) in the shebang.
This fixes the case (e.g. *BSD) where bash is installed on the host system, but not at the typical location of /bin.
Fix #[inline(always)] on closures with target feature 1.1
Fixes#108655. I think this is the most obvious solution that isn't overly complicated. The comment includes more justification, but I think this is likely better than demoting the `#[inline(always)]` to `#[inline]`, since existing code is unaffected.
Support interpolated block for `try` and `async`
I'm putting this up for T-lang discussion, to decide whether or not they feel like this should be supported. This was raised in #112952, which surprised me. There doesn't seem to be a *technical* reason why we don't support this.
### Precedent:
This is supported:
```rust
macro_rules! always {
($block:block) => {
if true $block
}
}
fn main() {
always!({});
}
```
### Counterpoint:
However, for context, this is *not* supported:
```rust
macro_rules! unsafe_block {
($block:block) => {
unsafe $block
}
}
fn main() {
unsafe_block!({});
}
```
If this support for `async` and `try` with interpolated blocks is *not* desirable, then I can convert them to instead the same diagnostic as `unsafe $block` and make this situation a lot less ambiguous.
----
I'll try to write up more before T-lang triage on Tuesday. I couldn't find anything other than #69760 for why something like `unsafe $block` is not supported, and even that PR doesn't have much information.
Fixes#112952
Remove Scope::Elision from bound-vars resolution.
This scope is a remnant of HIR-based lifetime resolution.
It's only role was to ensure that object lifetime resolution falled back to `'static`. This can be done using `ObjectLifetimeDefault` scope.
Get rid of subst-relate incompleteness in new solver
We shouldn't need subst-relate if we have bidirectional-normalizes-to in the new solver.
The only potential issue may happen if we have an unconstrained projection like `<Wrapper<?0> as Trait>::Assoc == <Wrapper<T> as Trait>::Assoc` where they both normalize to something that doesn't mention any substs, which would possibly prefer `?0 = T` if we fall back to subst-relate. But I'd prefer if we remove incompleteness until we can determine some case where we need them, and the bidirectional-normalizes-to seems better to have in general.
I can update https://github.com/rust-lang/trait-system-refactor-initiative/issues/26 and https://github.com/rust-lang/trait-system-refactor-initiative/issues/25 once this lands.

Tweak spans for self arg, fix borrow suggestion for signature mismatch
1. Adjust a suggestion message that was annoying me
2. Fix#112503 by recording the right spans for the `self` part of the `&self` 0th argument
3. Remove the suggestion for adjusting a trait signature on type mismatch, bc that's gonna probably break all the other impls of the trait even if it fixes its one usage 😅
Reuse the MIR validator for MIR inlining
Instead of having the inliner home-cook its own validation, we just check that the substituted MIR body passes the regular validation.
The MIR validation is first split in two: control flow validation (MIR syntax and CFG invariants) and type validation (subtyping relationship in assignments and projections). Only the latter can be affected by instantiating type parameters.
editor/code: Break down CI steps to know what is failing easily
This do the thing I mentioned in https://github.com/rust-lang/rust-analyzer/pull/15265#issuecomment-1634424385
This aims to improve CI status check more readable.
I tried to use [`jobs.<job_id>.if`](https://docs.github.com/en/actions/using-workflows/workflow-syntax-for-github-actions#jobsjob_idif) to make the configuration
more shortly once.
But it could not fire the `end-success` or `end-failure` status if some jobs in the workflow were skipped. This causes an integration problem with bors.
By their reasons, this patch still uses `jobs.<job_id>.steps[*].if`.

To do this change, we reorganize npm-script.
| previous | after |
|--------------------|----------------------------------------|
| `npm run lint` | `npm run lint && npm run format:check` |
| `npm run fix` | `npm run lint:fix && npm run format` |
The previous `npm run fix` sometimes does not complete fix automatically because ESLint's autofix doees not follow prettier's formatting. So we need to run `npm run lint:fix && npm run format` by this order.

limit `change_visibility` assist to applicable items
this pr limits the `change_visibility` assist to applicable items. top level items in this context means items that are not nested within `fn`s or `trait`s.
now
```rs
fn foo {
// assists on this `struct` keyword won't include `change_visibility`
struct Bar {}
}
trait Foo {
// same with the `fn` here
fn bar();
}
```
