…ebank Fix unused_assignments false positive Fixes rust-lang#22630. In liveness analysis, make `continue` jump to the loop condition's `LiveNode` (`cond` as in comment) instead of the loop's one (`expr`). https://github.com/rust-lang/rust/blob/069b0c410808c1d1d33b495e048b1186e9f8d57f/src/librustc/middle/liveness.rs#L1358-L1370
