f1c47c79fe Auto merge of #82058 - gilescope:to_digit_speedup, r=lcnr 
no need to check assertion on fast path as will always hold.

V small change. Easy to review though!

cb653b100c Document that assert! format arguments are evaluated lazily 
It can be useful to do some computation in `assert!` format arguments, in order to get better error messages. For example:

```rust
assert!(
    some_condition,
    "The state is invalid. Details: {}",
    expensive_call_to_get_debugging_info(),
);
```

It seems like `assert!` only evaluates the format arguments if the assertion fails, which is useful but doesn't appear to be documented anywhere. This PR documents the behavior and adds some tests.

090dac0c38 Auto merge of #81734 - richkadel:fixfordash, r=pnkfelix 
Ensures `make` tests run under /bin/dash (if available), like CI, and fixes a Makefile

Note: This cherrypicks #81688 (`@pnkfelix)`

Updates `tools.mk` to explicitly require `SHELL := /bin/dash`, since CI uses `dash` but other environments (including developer local machines) may default to `bash`.

Replaces bash-specific shell command in one Makefile with a dash-compatible alternative, and re-enables the affected Makefile test.

Removes apparently redundant definition of `UNAME`.

aee1e59e6f Simplify pattern grammar by allowing nested leading vert 
Along the way, we also implement a handful of diagnostics improvements
and fixes, particularly with respect to the special handling of `||` in
place of `|` and when there are leading verts in function params, which
don't allow top-level or-patterns anyway.

32-bit ARM: Emit `lr` instead of `r14` when specified as an `asm!` output register.

On 32-bit ARM platforms, the register `r14` has the alias `lr`. When used as an output register in `asm!`, rustc canonicalizes the name to `r14`. LLVM only knows the register by the name `lr`, and rejects it. This changes rustc's LLVM code generation to output `lr` instead.

closes #82052

cc ````@lcnr````

This was ICE'ing because we dont pass in the correct ``ParamEnv`` which meant that there was no ``Self: Foo`` predicate to make ``Self::Assoc`` well formed which caused an ICE when trying to normalize ``Self::Assoc`` in the mir interpreter
