Auto merge of #1880 - hyd-dev:rustup, r=oli-obk

Move `#[allow(unreachable_code)]` in `tests/run-pass/generator.rs`

The warning now appears on `yield 2;` instead of `drop(x)`: https://github.com/rust-lang/miri/runs/3429959882?check_suite_focus=true#step:8:265

`yield 2;` seems indeed unreachable so I adjusted the `#[allow]`.
