Tracking issue for NLL in Rust 2015

[carols10cents]

When NLL is enabled in Rust 2015, this part of the edition guide should get updated:

https://github.com/rust-lang-nursery/edition-guide/blame/5f3cc2a5618700efcde3bc00799744f21fa9ad2e/src/rust-2018/edition-changes.md#L6

I think this is the issue for NLL in 2015? rust-lang/rust#57895

This is the full NLL tracking issue: rust-lang/rust#43234
