Add a query for checking whether a function is an intrinsic.
work towards #93145
This will reduce churn when we add more ways to declare intrinsics

add suggestions to rc_clone_in_vec_init
A followup to https://github.com/rust-lang/rust-clippy/pull/8769
I also switch the order of the 2 suggestions, since the loop initialization one is probably the common case.
`@xFrednet` I'm not letting you guys rest for a minute 😅

rustdoc: Remove doc link resolution fallback to all `macro_rules` in the crate
This is a deny-by-default lint detecting such fallback for crater run, as discussed in https://github.com/rust-lang/rust/pull/96521.
Remove potentially misleading realloc parenthetical
This parenthetical is problematic, because it suggests that the following is sound:
```rust
let layout = Layout:🆕:<[u8; 32]>();
let p1 = alloc(layout);
let p2 = realloc(p1, layout, 32);
if p1 == p2 {
p1.write([0; 32]);
dealloc(p1, layout);
} else {
dealloc(p2, layout);
}
```
At the very least, this isn't the case for [ANSI `realloc`](https://en.cppreference.com/w/c/memory/realloc)
> The original pointer `ptr` is invalidated and any access to it is undefined behavior (even if reallocation was in-place).
and [Windows `HeapReAlloc`](https://docs.microsoft.com/en-us/windows/win32/api/heapapi/nf-heapapi-heaprealloc) is unclear at best (`HEAP_REALLOC_IN_PLACE_ONLY`'s description may imply that the old pointer may be used if `HEAP_REALLOC_IN_PLACE_ONLY` is provided).
The conservative position is to just remove the parenthetical.

`undocumented_unsafe_blocks` does not trigger on unsafe trait impls
Closes#8505
changelog: This lint checks unsafe impls NOT from macro expansions and checks ones in macro declarations.
~~`unsafe impl`s from macro invocations don't trigger the lint for now.~~
~~This lint checks unsafe impls from/not from macro expansions~~
Rename `eq_ignore_case` to `starts_with_ignore_case`
The method doesn't test for equality. It tests if the object starts with
a given byte array, so its name is confusing.
Don't lint `vec_init_then_push` when further extended
fixes#7071
This will still lint when a larger number of pushes are done (four currently). The exact number could be debated, but this is more readable then a sequence of pushes so it shouldn't be too large.
changelog: Don't lint `vec_init_then_push` when further extended.
changelog: Remove `mut` binding from `vec_init_then_push` when possible.
Rename `eval_order_dependence` to `mixed_read_write_expression`, move to nursery
As per the [reference](https://doc.rust-lang.org/1.51.0/reference/expressions.html#evaluation-order-of-operands) evaluation order is now defined.
I'm pretty sure rust always compiled with this evaluation order anyways so there's no reason the put an msrv limit on the lint.

Sync rustc_codegen_cranelift
Since the last sync there have mostly been fixes of various sorts. I also changed cg_clif from using a custom driver to `-Zcodegen-backend` when built as separate project. When built as part of rust it was already using `-Zcodegen-backend`.
