2ce1addeba Don't access pointer element type for nontemporal store 
Simply shift the bitcast from the store to the load, so that
we can use the destination type. I'm not sure the bitcast is
really necessary, but keeping it for now.

208173f8e9 Fix project_deref() implementation 
I'm not really sure what is wrong here, but I was getting load
type mismatches in the debuginfo code (which is the only place
using this function).

Replacing the project_deref() implementation with a generic
load_operand + deref did the trick.

4560efe46c Pass type when creating load 
This makes load generation compatible with opaque pointers.

The generation of nontemporal copies still accesses the pointer
element type, as fixing this requires more movement.

33e9a6b565 Pass type when creating atomic load 
Instead of determining it from the pointer type, explicitly pass
the type to load.

3eff244fc7 Auto merge of #85832 - kornelski:raw_arg, r=yaahc 
Unescaped command-line arguments for Windows

Some Windows commands, expecially `cmd.exe /c`, have unusual quoting requirements which are incompatible with default rules assumed for `.arg()`.

This adds `.unquoted_arg()` to `Command` via Windows `CommandExt` trait.

Fixes #29494

Remove lints_enabled

r? `@camsteffen`

cc https://github.com/rust-lang/rust-clippy/pull/7448#issuecomment-876497862

I haven't added a variant with `last_node_with_lint_attrs` yet, since I didn't see a usecase for this. Also this field is not documented, so I'm wondering how it behaves with command line lints and so on.

e916b7cb77 Auto merge of #86888 - FabianWolff:issue-86600, r=davidtwco 
Fix double warning about illegal floating-point literal pattern

This PR fixes #86600. The problem is that the `ConstToPat` struct contains a field `include_lint_checks`, which determines whether lints should be emitted or not, but this field is currently not obeyed at one point, leading to a warning being emitted more than once. I have fixed this behavior here.

Stop generating `alloca`s & `memcmp` for simple short array equality

Example:
```rust
pub fn demo(x: [u16; 6], y: [u16; 6]) -> bool { x == y }
```

Before:
```llvm

start:
  %y = alloca [6 x i16], align 8
  %x = alloca [6 x i16], align 8
  %.0..sroa_cast = bitcast [6 x i16]* %x to i96*
  store i96 %0, i96* %.0..sroa_cast, align 8
  %.0..sroa_cast3 = bitcast [6 x i16]* %y to i96*
  store i96 %1, i96* %.0..sroa_cast3, align 8
  %_11.i.i.i = bitcast [6 x i16]* %x to i8*
  %_14.i.i.i = bitcast [6 x i16]* %y to i8*
  %bcmp.i.i.i = call i32 `@bcmp(i8*` nonnull dereferenceable(12) %_11.i.i.i, i8* nonnull dereferenceable(12) %_14.i.i.i, i64 12) #2, !alias.scope !2
  %2 = icmp eq i32 %bcmp.i.i.i, 0
  ret i1 %2
}
```
```x86

Rename run_lints -> lints_enabled

Just a quick rename of a utilities function. `run_lints` kinda suggested that the lints were run by this function. But the only thing this function does is to check if the lints are enabled in the context of the `hir_id`
