A recent LLVM change causes some changes here, if I'm understanding correctly it allows some better latency reduction. From what I can tell, this test doesn't care that only a single register is used, so we use -DAG instead of -NEXT to allow some instruction reordering. By happy coincidence, the z10 and z13 code matches now, which collapsed some of the test lines. I'm happy to split them back out if that's bad for some reason though!
To explain some non-obvious things that took me some time to work out.
`EarlyLintPassObjects` is an old name.
As `*CombinedLateLintModPass`, because that matches things like `late_lint_mod`.
We generally write `lint_pass`/`LintPass`. This commit renames some things that only use `pass`/`Pass`. And also some `s/module/mod` changes, too.
There are `register_*_lint_pass` methods, might as well go through them.

Use infer tys for synthetic params when lowering const paths point to fns
```rust
#![feature(min_generic_const_args)]
trait Trait {}
impl<'t> Trait for [(); N] {}
fn N(arg: impl Trait) {}
```
1. `arg: impl Trait` implies a synthetic param `<impl Trait>` and the obligation `_: Trait`;
2. when matching `impl Trait for [(); N]`, lowering const arg `N` fills in that synthetic param, so the impl header contains `<[(); N::<impl Trait>] as Trait>`;
3. then instantiating this header with the impl's args causing a param/arg mismatch and ICE.
This PR uses infer tys for synthetic params. Although this will emit the error in `ItemCtxt` because infer tys are not allowed here. I think that is reasonable, because `N` omits the synthetic parameter, though we cannot write the ty explicitly anywhere.
Fixes rust-lang#155834
add crashtests [1/N] There are currently very few crashtests for issues created in the last year. Let's start adding some again.
