SGX target: convert a bunch of panics to aborts

Fixes https://github.com/fortanix/rust-sgx/issues/86, https://github.com/fortanix/rust-sgx/issues/103 and in general protect preemptively against Iago attacks by aborting instead of unwinding in potentially unexpected situations.

Rollup merge of #59444 - cuviper:steps_between, r=scottmcm
Implement useful steps_between for all integers

We can use `usize::try_from` to convert steps from any size of integer.
This enables a meaningful `size_hint()` for larger ranges, rather than
always just `(0, None)`. Now they return the true `(len, Some(len))`
when it fits, otherwise `(usize::MAX, None)` for overflow.

Rollup merge of #59286 - cramertj:async-fn-ret-ty, r=varkor
Refactor async fn return type lowering

async fn now lowers directly to an existential type declaration
rather than reusing the `impl Trait` return type lowering.

As part of this, it lowers all argument-position elided lifetimes
using the in-band-lifetimes machinery, creating fresh parameter
names for each of them, using each lifetime parameter as a generic
argument to the generated existential type.

This doesn't currently successfully allow multiple
argument-position elided lifetimes since `existential type`
doesn't yet support multiple lifetimes where neither outlive
the other:
```rust
existential type Foo<'a, 'b>:; // error: ambiguous lifetime bound in `impl Trait`
fn foo<'a, 'b>(_: &'a u8, _: &'b u8) -> Foo<'a, 'b> { () }
```

This requires a separate fix.

Rollup merge of #59262 - timvermeulen:iterator_cmp_dedup, r=scottmcm
Remove duplicated code from Iterator::{ne, lt, le, gt, ge}

This PR delegates `Iterator::ne` to `Iterator::eq` and `Iterator::{lt, le, gt, ge}` to `Iterator::partial_cmp`.

Oddly enough, this change actually simplifies the generated assembly [in some cases](https://rust.godbolt.org/z/riBtNe), although I don't understand assembly well enough to see if the longer assembly is doing something clever.

I also added two extremely simple benchmarks:
```
// before
test iter::bench_lt               ... bench:      98,404 ns/iter (+/- 21,008)
test iter::bench_partial_cmp      ... bench:      62,437 ns/iter (+/- 5,009)

// after
test iter::bench_lt               ... bench:      61,757 ns/iter (+/- 8,770)
test iter::bench_partial_cmp      ... bench:      62,151 ns/iter (+/- 13,753)
```

I have no idea why the current `lt`/`le`/`gt`/`ge` implementations don't seem to be compiled optimally, but simply having them call `partial_cmp` seems to be an improvement.

See #44729 for a previous discussion.
