A rust-enabled gdb already knows how to display string slices, structs, tuples, and enums (and after rust-lang#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.
Fix missing ',' array element separators and convert NaN's to 0.
Hopefully will speed up CI slightly!
This is a follow up to 8aa9267 which changed the driver to use lld directly rather than invoking it through Clang. This change ensures we pass all the necessary flags to lld.
It used to point to the implementation PR.

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]);
```
