rust/src/test/compile-fail/regions-free-region-ordering-callee-4.rs
Niko Matsakis dbf994bbaf Make RFC 1214 warnings into errors, and rip out the "warn or err"
associated machinery. Future such attempts should go through lints
anyhow.

There is a fair amount of fallout in the compile-fail tests, as WF
checking now occurs earlier in the process.
