refactor(attribute parser): move check_custom_mir to attribute parser

Part of rust-lang/rust#153101

r? @JonathanBrouwer

Auto generate trait name from first method.

Input:

```rust
impl S$0 {
    fn foo() {}
}
```

Old output:

```rust
trait NewTrait {
    fn foo();
}

impl NewTrait for S {
    fn foo() {}
}
```

This PR output:

```rust
trait Foo {
    fn foo();
}

impl Foo for S {
    fn foo() {}
}
```

llvm: Update `reliable_f128` configuration for LLVM22 on Sparc

LLVM22 should have resolved issues with the `f128` ABI, meaning we can now set `cfg(target_has_reliable_f128)` on the platform.

vec::Drain::fill: avoid reference to uninitialized memory

`range_slice` points to memory that is not initialized (e.g. it might be dropped `Box`/`String`). Let's avoid that and instead use an index-based loop.

test copy_specializes_from_vecdeque: reduce iteration count for Miri

This test currently takes >20s and that doesn't really seem worth it.

These methods are just wrappers around the intrinsics.

Stash parse errors when pasing rtn that doesn't use `(..)`.
Emit single error on `Foo::bar(qux)` that looks like rtn in incorrect position and suggest `Foo::bar(..)`.
```
error: return type notation not allowed in this position yet
  --> $DIR/let-binding-init-expr-as-ty.rs:18:10
   |
LL | struct K(S::new(()));
   |          ^^^^^^^^^^
   |
help: furthermore, argument types not allowed with return type notation
   |
LL - struct K(S::new(()));
LL + struct K(S::new(..));
   |
```
On incorrect rtn in let binding type for an existing inherent associated function, suggest `:` -> `=` to turn the "type" into a call expression.
```
error: expected type, found associated function call
  --> $DIR/let-binding-init-expr-as-ty.rs:29:12
   |
LL |     let x: S::new(());
   |            ^^^^^^^^^^
   |
help: use `=` if you meant to assign
   |
LL -     let x: S::new(());
LL +     let x = S::new(());
   |
```

This improves startup performance by 16%, shown by an optimized
hello-world program. glibc's `pthread_getattr_np` performs expensive
syscalls when reading `/proc/self/maps`. That is all wasted with
`panic = immediate-abort` active because `init()` immediately discards
the return value from `install_main_guard()`. A similar improvement can
be seen in environments that don't have `/proc`. This change is safe
because the immediately succeeding comment says that we rely on Linux's
"own stack-guard mechanism".

Replace direct usage of make with syntax factory and migrate assist to syntaxEditor
