VecGraph + misc
It's required for the next commit. Note that you can still have `G = &H`, since there are implementations of all the graph traits for references.

There was a problem hiding this comment.
nit: could you add a basic test or two for the predecessors functionality? (I think you also need to update some of the existing tests to compile with the extra generic parameter) 🙂
There was a problem hiding this comment.
I did not need to update existing tests, since the new generic parameter has a default.
I added a test for predecessors + added predecessor-aware mode for existing tests (so that we are more sure that enabling predecessors doesn't break other stuff).

…int, r=compiler-errors Add a lint against never type fallback affecting unsafe code ~~I'm not very happy with the code quality... `VecGraph` not allowing you to get predecessors is very annoying. This should work though, so there is that.~~ (ended up updating `VecGraph` to support getting predecessors) ~~First few commits are from rust-lang#123934 rust-lang#123980
