fix subtle bug in NLL type checker
...
The bug was revealed by the behavior of the old-lub-glb-hr-noteq1.rs
test. The old-lub-glb-hr-noteq2 test shows the current 'order dependent'
behavior of coercions around higher-ranked functions, at least when
running with `-Zborrowck=mir`.
Also, run compare-mode=nll.

remove snapshot calls from "match" operations during select
...
Motivation:
- we want to use leak-check sparingly, first off
- these calls were essentially the same as doing the check during subtyping

modify leak-check to track only outgoing edges from placeholders
...
Also, update the affected tests. This seems strictly better but it is
actually more permissive than I initially intended. In particular it
accepts this
```
forall<'a, 'b> {
exists<'intersection> {
'a: 'intersection,
'b: 'intersection,
}
}
```
and I'm not sure I want to accept that. It implies that we have a
`'empty` in the new universe intoduced by the `forall`.

This doesn't mention that using an existing lifetime is possible, but
that would hopefully be clear as always being an option. The intention

Reference tracking issue for inherent associated types in diagnostic
This makes it clearer that associated types in inherent impls are an intended feature, like the diagnostic for equality constraints in where clauses. (This is more helpful, because the lack of associated types is a confusing omission and it lets users more easily track the state of the feature.)
