these are fixed by polonius=legacy, are currently accepted by
polonius=next but won't be by the alpha analysis

Add a lot of NLL `known-bug` tests

r? `@jackh726`

As requested in rust-lang#143093 (review) this extracts most tests from that PR and expands upon them as described.

The handful of linked-list cursor-like tests will also turn into polonius=next known-bugs in rust-lang#143093 where the behavior w/r/t kills changes of course.
