internal: support `#[rustc_coinductive]`
rust-lang/rust#100386 changed the trait solver so that `Sized` is treated as coinductive trait, just like auto traits. This is now controlled by the perma-unstable `#[rustc_coinductive]` attribute (rust-lang/rust#108033), which this PR adds support for.
In practice, I don't think this matters much if at all. Currently we don't give chalk enough information so chalk cannot precisely (dis)prove `Sized` bounds.
[`unused_async`]: don't lint if function is part of a trait
Fixes#10459.
We shouldn't lint if the function is part of a trait, because the user won't be able to easily remove the `async`, as this will then not match with the function signature in the trait definition

editor/code: Use `@tsconfig/strictest` to define type checking rules
Motivation
-----------
This change aims to make it easier to manage tsconfig by [``@tsconfig/strictest`](https://www.npmjs.com/package/@tsconfig/strictest)` and intend to leave to create "ideal" rules about TypeScript's type checking.
Implementation
---------------
This change removes some duplicated rules defined in ``@tsconfig/strictest`` and add disabing some strict rules that fails with the current codebase.
Validate fluent variable references in tests
Closes#101109
Under `cfg(test)`, the `fluent_messages` macro will emit a list of variables referenced by each message and its attributes. The derive attribute will now emit a `#[test]` that checks that each referenced variable exists in the structure it's applied to.
Use substring matching for TESTNAME
Restores the previous behaviour of matching using a substring match rather than needing a full match
changelog: none
To make it easier to verify that the output snapshots have been migrated
faithfully, this change adds some temporary helper code that lets us avoid
having to completely re-bless the existing snapshots.
A later change in this PR will then re-bless the tests and remove the temporary
helper code.
Currently a test without a `failure-status` directive is treated as having an
expected failure-status of 1, but `run-coverage` tests will want to treat those
tests as expecting success instead.
This will allow the `run-coverage` mode to easily set environment variable
`LLVM_PROFILE_FILE`, and to prevent the executable from being deleted after a
successful run.
mir opt + codegen: handle subtyping
fixes#107205
the same issue was caused in multiple places:
- mir opts: both copy and destination propagation
- codegen: assigning operands to locals (which also propagates values)
I changed codegen to always update the type in the operands used for locals which should guard against any new occurrences of this bug going forward. I don't know how to make mir optimizations more resilient here. Hopefully the added tests will be enough to detect any trivially wrong optimizations going forward.
`Path::with_extension` used to reallocate (and copy) paths twice per
call, now it does it once, by checking the size of the previous and new
extensions it's possible to call `PathBuf::with_capacity` and pass the
exact capacity it takes.
Also reduce the memory consumption of the path returned from
`Path::with_extension` by using exact capacity instead of using
amortized exponential growth.
