bd91c94a5d Rollup merge of #104269 - compiler-errors:hang-in-where-clause-sugg, r=lcnr 
Fix hang in where-clause suggestion with `predicate_can_apply`

Using `predicate_may_hold` during error reporting causes an evaluation overflow, which (because we use `evaluate_obligation_no_overflow`) then causes the predicate to need to be re-evaluated locally, which results in a hang.

... but since the "add a where clause" suggestion is best-effort, just throw any overflow errors. No need for 100% accuracy.

r? `@lcnr` who has been thinking about overflows... Let me know if you want more context about this issue, and as always, feel free to reassign.

4e0d0d757e Auto merge of #102750 - the8472:opt-field-order, r=wesleywiser 
optimize field ordering by grouping m*2^n-sized fields with equivalently aligned ones

```rust
use std::ptr::addr_of;
use std::mem;

struct Foo {
    word: u32,
    byte: u8,
    ary: [u8; 4]
}

fn main() {
    let foo: Foo = unsafe { mem::zeroed() };

    println!("base: {:p}\nword: {:p}\nbyte: {:p}\nary:  {:p}", &foo, addr_of!(foo.word), addr_of!(foo.byte), addr_of!(foo.ary));
}
```

prints

```
base: 0x7fffc1a8a668
word: 0x7fffc1a8a668
byte: 0x7fffc1a8a66c
ary:  0x7fffc1a8a66d
```

I.e. the `u8` in the middle causes the array to sit at an odd offset, which might prevent optimizations, especially on architectures where unaligned loads are costly.

Note that this will make field ordering niche-dependent, i.e. a `Bar<T>` with `T=char` and `T=u32` may result in different field order, this may break some code that makes invalid assumptions about `repr(Rust)` types.

Fix --extern library finding errors

- `crate_name` is not specified/passed to `metadata_crate_location_unknown_type`
c493bae0d8/compiler/rustc_error_messages/locales/en-US/metadata.ftl (L274-L275)
- `metadata_lib_filename_form` is missing `$`
- Add additional check to ensure that library is file

Testing
1. Create file `a.rs`
```rust
extern crate t;
fn main() {}
```
1. Create empty file `x`
1. Create empty directory `y`
1. Run
```sh
$ rustc -o a a.rs --extern t=x
$ rustc -o a a.rs --extern t=y
```
Both currently panic with stable.

a673364c54 Rollup merge of #104359 - Nilstrieb:plus-one, r=fee1-dead 
Refactor must_use lint into two parts

Before, the lint did the checking for `must_use` and pretty printing the types in a special format in one pass, causing quite complex and untranslatable code.
Now the collection and printing is split in two. That should also make it easier to translate or extract the type pretty printing in the future.

Also fixes an integer overflow in the array length pluralization
calculation.

Add powerpc64-ibm-aix as Tier-3 target

This is part of the effort mentioned in https://github.com/rust-lang/compiler-team/issues/553.

A reference to these options are definitions from [clang](ad6fe32032/clang/lib/Basic/Targets/PPC.h (L414-L448)) and [llvm](https://github.com/llvm/llvm-project/blob/main/llvm/lib/Target/PowerPC/PPCTargetMachine.cpp).

AIX has a system `ld` but [its options and behaviors](https://www.ibm.com/docs/en/aix/7.3?topic=l-ld-command) are different from GNU ld. Thanks to ``@bzEq`` for contributing the linking args.
