This is a follow up to 8aa9267 which changed the driver to use lld

When popping in CTFE, perform validation before jumping to next statement to have a better span for the error

Currently, when validating the return value fails, the span points at the next statement after the call. That does not make much sense.

Rollup merge of #55869 - SimonSapin:iterate, r=alexcrichton
Add std::iter::unfold

This adds an **unstable** ~`std::iter::iterate`~ `std::iter::unfold` function and ~`std::iter::Iterate`~ `std::iter::Unfold` type that trivially wrap a ~`FnMut() -> Option<T>`~ `FnMut(&mut State) -> Option<T>` closure to create an iterator. ~Iterator state can be kept in the closure’s environment or captures.~

This is intended to help reduce amount of boilerplate needed when defining an iterator that is only created in one place. Compare the existing example of the `std::iter` module: (explanatory comments elided)

```rust
struct Counter {
    count: usize,
}

impl Counter {
    fn new() -> Counter {
        Counter { count: 0 }
    }
}

impl Iterator for Counter {
    type Item = usize;

    fn next(&mut self) -> Option<usize> {
        self.count += 1;
        if self.count < 6 {
            Some(self.count)
        } else {
            None
        }
    }
}
```

… with the same algorithm rewritten to use this new API:

```rust
fn counter() -> impl Iterator<Item=usize> {
    std::iter::unfold(0, |count| {
        *count += 1;
        if *count < 6 {
            Some(*count)
        } else {
            None
        }
    })
}
```

-----

This also add unstable `std::iter::successors` which takes an (optional) initial item and a closure that takes an item and computes the next one (its successor).

```rust
let powers_of_10 = successors(Some(1_u16), |n| n.checked_mul(10));
assert_eq!(powers_of_10.collect::<Vec<_>>(), &[1, 10, 100, 1_000, 10_000]);
```

Rollup merge of #55767 - tromey:disable-some-pretty-printers, r=alexcrichton
Disable some pretty-printers when gdb is rust-enabled

A rust-enabled gdb already knows how to display string slices,
structs, tuples, and enums (and after #54004, the pretty-printers
can't handle enums at all).  This patch disables these pretty-printers
when gdb is rust-enabled.

The "gdb-pretty-struct-and-enums-pre-gdb-7-7.rs" test is renamed,
because it does not seem to depend on any behavior of that version of
gdb, and because gdb 7.7 is 4 years old now.

Suggest correct syntax when writing type arg instead of assoc type

- When confusing an associated type with a type argument, suggest the appropriate syntax. Given `Iterator<isize>`, suggest `Iterator<Item = isize>`.

- Point at associated type def span for context.
- Point at each extra type argument.

rustc_target: separate out an individual alignment quantity type from Align.

Before this PR, `rustc_target::abi::Align` combined "power-of-two alignment quantity" semantics, with a distinction between ABI (required) and preferred alignment (by having two quantities).

After this PR, `Align` is only *one* such quantity, and a new `AbiAndPrefAlign` type is introduced to hold the pair of ABI and preferred `Align` quantities.

`Align` is used everywhere one quantity is necessary/sufficient, simplifying some of the code in codegen/miri, while `AbiAndPrefAlign` only in layout computation (to propagate preferred alignment).

00e03ee574 Auto merge of #56143 - nikomatsakis:issue-56128-segment-id-ice-nightly, r=petrochenkov
Issue 56128 segment id ice nightly

Tentative fix for #56128

From what I can tell, the problem is that if you have `pub(super) use foo::{a, b}`, then when we explode the `a` and `b`, the segment ids from the `super` path were not getting cloned. However, once I fixed *that*, then I ran into a problem that the "visibility" node-ids were not present in the final HIR -- this is because the visibility of the "stem" that is returned in this case was getting reset to inherited. I don't *think* it is a problem to undo that, so that the visibility is returned unmodified.

Fixes #55475
