3beb2e95a9 Expand assert!(expr) to panic() function instead of panic!() macro.
The panic message might contain braces which should never be
interpreted as format placeholders, which panic!() will do in a future
edition.

da66a501f6 Specialize panic_fmt lint for the {core,std}::panic!() macros.
It now only reacts to expansion of those macros, and suggests

normalize substs while inlining

fixes #68347 or more precisely, this fixes the same ICE in rust analyser as veloren is pinned to a specific nightly
and had an error with the current one.

I didn't look into creating an MVCE here as that seems fairly annoying, will spend a few minutes doing so rn. (failed)

98e16884b1 Auto merge of #78058 - bugadani:arena2, r=lcnr
Make sure arenas don't allocate bigger than HUGE_PAGE

Right now, arenas allocate based on the size of the last chunk. It is possible for a `grow` call to allocate a chunk that is not a multiple of `PAGE`, and this size is doubled for each subsequent allocation. This means, instead of `HUGE_PAGE`, the biggest page possible is actually unknown.

This change fixes this, and also removes an unnecessary checked multiplication. It is still possible to allocate bigger than `HUGE_PAGE` pages, but this will only happen as many times as absolutely necessary.

Make set_span take mut self

This was a mistake in https://github.com/rust-lang/rust/pull/77614

It's not a _huge_ deal, because backends can always implement this with interior mutability, but it's nice to avoid interior mutability when possible. For context, the `set_source_location` method, called alongside `set_span`, also takes `&mut self`.

7b33ae642e Improve wording of "cannot multiply" type error
For example, if you had this code:

    fn foo(x: i32, y: f32) -> f32 {
        x * y
    }

You would get this error:

    error[E0277]: cannot multiply `f32` to `i32`
     --> src/lib.rs:2:7
      |
    2 |     x * y
      |       ^ no implementation for `i32 * f32`
      |
      = help: the trait `Mul<f32>` is not implemented for `i32`

However, that's not usually how people describe multiplication. People
usually describe multiplication like how the division error words it:

    error[E0277]: cannot divide `i32` by `f32`
     --> src/lib.rs:2:7
      |
    2 |     x / y
      |       ^ no implementation for `i32 / f32`
      |
      = help: the trait `Div<f32>` is not implemented for `i32`

So that's what this change does. It changes this:

    error[E0277]: cannot multiply `f32` to `i32`
     --> src/lib.rs:2:7
      |
    2 |     x * y
      |       ^ no implementation for `i32 * f32`
      |
      = help: the trait `Mul<f32>` is not implemented for `i32`

To this:

    error[E0277]: cannot multiply `i32` by `f32`
     --> src/lib.rs:2:7
      |
    2 |     x * y
      |       ^ no implementation for `i32 * f32`
      |
      = help: the trait `Mul<f32>` is not implemented for `i32`

`DiagnosticMetadata.current_function` is only used for these messages so tweaking its behavior should be ok.

resolve: Do not put nonexistent crate `meta` into prelude

Before the 2018 edition release there was some vague suggestion about adding a crate named `meta` to the standard distribution.
On this basis the name `meta` was "partially reserved" by putting `meta` into extern prelude (this means importing something named `meta` will result in an ambiguity error, for example).
This only caused confusion so far, and two years later there are no specific plans to add such crate.

If some standard crate (named `meta` or not) is added in the future, then cargo will hopefully already have ability to put it into extern prelude explicitly through `Cargo.toml`.
Otherwise, it could be added to extern prelude by the compiler at edition boundary.

ffeeb20398 Auto merge of #77373 - jonas-schievink:rm-rf-copy-prop, r=oli-obk
Remove the old copy propagation pass

This pass was added a long time ago, and has not really seen much improvement since (apart from some great work in https://github.com/rust-lang/rust/pull/76569 that unfortunately ran into preexisting soundness issues). It is slow and unsound, and we now have a destination propagation pass that performs a related optimization and could be extended.
